Merge v1.29.0: 'new device' red-dot flag

feat v1.29.0: 'new device' flag with a red dot
- auto devices/light groups appearing after install get a server-side 'new' flag (settings.new_device_ids) and a red dot top-right of the icon; opening the device's editor clears it for every client - known_devices baseline seeded silently on first run — upgrades never flood the plan with dots; hand-made markers never flagged - pure diffNewDevices + unit tests; backend schema; smoke_new_device.mjs; TESTING.md row

 ### Step 2. Outline the rooms

-After the first space is added, the card switches to markup mode by itself. Click grid points, connecting them with lines, and close the room outline by clicking the first point.
+After the first space is added, the card switches to the **Plan** tab by itself. The card has three mode tabs in the header — **View** (default: display and device control only, nothing can be moved or edited), **Plan** (rooms, openings, labels, space settings) and **Devices** (placing and configuring markers); the edit tabs are shown to administrators. In Plan, click grid points, connecting them with lines, and close the room outline by clicking the first point.

 As soon as the outline is closed, the room-save dialog appears. Here you need to **bind the room to a Home Assistant area** — this is exactly what enables the automation. For utility rooms with no devices (hall, sauna) there is a **"No area"** button.

 ![Marking up a room and saving it](docs/images/05-room-dialog.png)

+While drawing, a ruler follows the cursor showing the current segment's real length (metres, or feet + inches on an imperial Home Assistant). The scale is set per space — the **"Scale (grid cell size)"** field in the space dialog says how many centimetres one grid cell represents (default 5 cm).
+
+Rooms may not overlap: a click strictly inside an existing room, or an outline that would swallow one, is refused. Two more tools help you reshape the plan later:
+
+- **Merge** — click a room, then a neighbour that shares a wall; they fuse into one. A dialog picks which name and area survive.
+- **Split** — click a room, then two points on its walls; the chord cuts it in two. The bigger part stays the room it was (name, area, devices); the smaller one asks for a new name and area.
+
+
+### Doors, windows and locks
+
+In markup mode the **"Opening"** tool places doors and windows: click next to a wall and the
+opening snaps onto it. Pick the type, the **length in real centimetres** (defaults: door 90 cm,
+window 120 cm), an open/close sensor and — for doors — a **lock entity**.
+
+With a sensor bound, the plan comes alive: the door leaf swings on its hinge and the swing arc
+draws itself in as the real door opens; a window opens its two casements. While open, the moving
+parts take an accent colour. A door with a lock shows a padlock badge next to it — green when
+locked, orange when unlocked. For safety the lock can **not** be toggled from the plan; a click
+on the opening shows a status card with both states instead.
+
+Openings are easy to adjust later: hovering one highlights it, you can **drag it along the
+walls** (it slides around corners too), and a **double click opens its properties**.
+
 ### Step 3. Devices appear by themselves

 As soon as you save a room bound to an area, **the devices of that area are automatically laid out inside the outline**. These are the same devices shown on the **Settings → Devices → (filtered by the room)** page — only the meaningful ones, without service records, bridges and duplicates.

 Not everything has to be left to the automation.

Set a name, icon, model, link, description and, if you wish, attach a **PDF manual**.

+The same dialog controls how the device looks on the plan. **Display** switches between the
+icon badge, an animated **presence ripple** (pulsing rings while the entity is active, a faint
+dot when idle — great for motion sensors) or both, with a per-device ring colour and size. The

 ![Разметка комнаты и её сохранение](docs/images/05-room-dialog.png)

+Во время рисования у курсора показывается линейка с реальной длиной текущего отрезка (метры или футы+дюймы на имперской системе HA). Масштаб задаётся для каждого пространства — поле **«Масштаб (размер ячейки сетки)»** в диалоге пространства: сколько сантиметров в одной ячейке (по умолчанию 5 см).
+
+Комнаты не могут пересекаться: клик строго внутри существующей комнаты или контур, охватывающий её, отклоняются. Ещё два инструмента помогают перекроить план позже:
+
+- **Объединить** — кликните комнату, затем соседнюю с общей стеной; они сольются в одну. Диалог выбирает, чьё имя и зона останутся.
+- **Разделить** — кликните комнату, затем две точки на её стенах; хорда разрежет её надвое. Бо́льшая часть остаётся прежней комнатой (имя, зона, устройства), меньшая просит новое имя и зону.
+
+
+### Двери, окна и замки
+
+В режиме разметки инструмент **«Проём»** ставит двери и окна: кликните рядом со стеной — проём
+примагнитится к ней. Выберите тип, **длину в реальных сантиметрах** (по умолчанию дверь 90 см,
+окно 120 см), датчик открытия и — для двери — **замок**.
+
+С привязанным датчиком план оживает: створка двери поворачивается на петле, и дуга распахивания
+дорисовывается по мере открытия настоящей двери; окно раскрывает две створки. Пока открыто,
+подвижные части подсвечены акцентным цветом. У двери с замком рядом отображается замочек —
+зелёный, когда заперто, оранжевый, когда нет. Ради безопасности замок с плана **нельзя**
+переключить — клик по проёму показывает карточку с обоими статусами.
+
+Проёмы легко поправить позже: при наведении проём подсвечивается, его можно **перетащить вдоль
+стен** (в том числе за угол), а **двойной клик открывает свойства**.
+
 ### Шаг 3. Устройства появляются сами

 Как только вы сохранили комнату с привязкой к зоне, **устройства этой зоны автоматически расставляются внутри контура**. Берутся те же устройства, что показаны на странице **Настройки → Устройства → (фильтр по нужной комнате)** — только осмысленные, без служебных записей, мостов и дубликатов.

+## Room geometry rules (v1.19–v1.21)
+
+A **line is never an entity of its own**: walls are *derived* from room outlines
+(`roomEdges`, deduped by `segKey`), so an abandoned outline leaves nothing behind and deleting
+a room keeps the walls its neighbours still contribute. Rooms may not overlap
+(`pointStrictlyInside` + `roomsOverlap`; being ON a shared wall is legal — real neighbouring
+walls overlap collinearly rather than match exactly). **Merge/Split** use boolean geometry from
+**polyclip-ts** (chosen over `polygon-clipping`, whose ESM build exports only a default while
+its types declare named exports — breaking either tsc or the runtime): merge accepts a pair only
+when the union collapses into one hole-free outline; split cuts wall-to-wall with a chord, the
+bigger part keeps the room identity (name/area/devices).
+
 ## Markup editor (v1.4.0+)

-State inside the card: `_markup` (mode), `_tool` (draw/erase/delroom), `_path` (the current outline,
-vertices on the GRID_N=60 grid). Clicks on the stage → `_svgPoint`→`_snap`. Each pair of points adds a
-segment to `space.segments` (dedup by key, saved via config/set with debounce). The outline is closed
+State inside the card: `_markup` (mode), `_tool` (draw/delroom), `_path` (the current outline,
+vertices on the GRID_N=240 grid). Clicks on the stage → `_svgPoint`→`_snap`. The outline is closed
 = a click on the first vertex → area select (hass.areas) + name → room {poly}. Polygon rooms and
 rectangles are rendered uniformly (hit-test: point-in-polygon / rect).

+**A line is never an entity of its own (v1.19.0).** Nothing is persisted while you draw: an
+outline you never close leaves no trace. Walls are *derived* from the room outlines by
+`roomEdges(rooms)` (logic.ts) and deduped by `segKey`, so a wall shared by two rooms is emitted
+once — deleting a room therefore keeps the borders its neighbours still contribute and drops the
+rest, with no bookkeeping. The legacy `space.segments` array is stripped on every save (validation
+still tolerates it on read; see CHANGELOG v1.19.0).
+
+While drawing, the length of the current segment follows the cursor (`_fmtLen` → `segmentCm`/
+`formatLength`): metres, or feet+inches when `hass.config.unit_system` is imperial. The scale is
+per-space `cell_cm` — cm represented by one grid cell (default 5, so 240 cells ≈ 12 m).
+
+## Doors & windows (v1.23.0+)
+
+`space.openings[]` — plan geometry, **not** markers: an opening needs an angle, a length and a
+wall, while markers are free points whose positions live in the layout store. Model:
+`{id, type: door|window, x, y, angle, length, contact?, lock?, invert?, flip_h?, flip_v?}`
+(normalized coords; `length` normalized by plan width). Placement snaps onto the nearest
+**derived** wall via `snapToWall` (logic.ts) — the angle is normalized to [-90, 90) because two
+rooms share a wall with opposite edge directions, and without that a drag across segment
+boundaries flips the hinge. The opening then keeps **absolute coordinates**, so editing, merging
+or deleting rooms never breaks it.
+
+Rendering (after easy-floorplan, MIT): SVG symbol at the origin (jambs + hinged leaf + a
+quarter-circle arc revealed via `stroke-dashoffset`), translated/rotated onto the wall; windows
+are two casement leaves. `openingAmount` (pure) maps the contact state to 0..1: no sensor →
+door drawn open / window closed (static-plan convention); `unavailable`/`unknown` freeze that
+default. The lock renders as an HTML padlock badge (`.oplock`) in the device layer; a lock is
+**never** toggled from the plan (TOGGLE_FORBIDDEN_DOMAINS rule). View-mode UX: hover outline,
+drag along walls (continuous re-snap, saved on release), click → status card (250 ms timer),
+double click → properties dialog. In markup mode the "Opening" tool handles clicks instead.

 # Changelog

+## v1.29.0 — 2026-07-22 (the "new device" flag)
+- **Devices that appear in HA after installation no longer show up silently**:
+  an auto-placed device (or light group) gets a big red dot at the top-right of
+  its icon. The flag is stored server-side (`settings.new_device_ids`), so every
+  client sees it — and it disappears everywhere the first time someone opens
+  that device's editor.
+- The baseline of known devices is seeded silently on the first run after the
+  update, so **existing devices never flood the plan with dots**. Hand-made
+  markers (virtual/rebindings) are never flagged — the user just created them.
+  (Pure `diffNewDevices`, unit-tested; backend schema for the two new settings.)
+
+## v1.28.1 — 2026-07-22 (View-mode polish: cursors and inert openings)
+- **Device icons in View no longer show the grab cursor** (drag lives in the
+  Devices mode); they show a pointer — clicking still works exactly as before.
+- **Doors and windows in View are pure drawings**: no grab cursor, no hover
+  outline, no hit target, no click — regardless of what is bound to them.
+- **The lock badge is the one exception**: when a lock is bound, the badge is
+  shown and clickable in View (pointer cursor, click opens the door/lock info
+  card). It stays inert in Plan so it does not fight editing.
+- In Plan an opening remains fully interactive: grab cursor + hover outline,
+  dragging along walls, and a click with ANY tool opens its properties dialog.
+
+## v1.28.0 — 2026-07-21 (sub-area rooms: manual placement without an HA area; issue #3)
+- **Devices can now be placed into rooms that have no Home Assistant area.**
+  The marker dialog's room list includes area-less rooms (marked "no area,
+  manual"); pick one and the device/virtual marker lands at its centre. The
+  marker stores `room_id`, so the choice survives edits and re-opens. The
+  laundry-cupboard case from issue #3: a decorative room inside a larger area
+  can now hold its own door sensor and light.
+- Room reference parsing extracted as pure `parseRoomRef` (`space#area` /
+  `space#@roomId`), unit-tested; backend schema for `room_id`.
+
+## v1.27.0 — 2026-07-21 (RGB light colors + alarm pulse; issue #3)
+- **RGB lights show their actual color**: an "on" light with a color tints its
+  bulb icon, glow and — unless a custom ripple color is set — its presence ripple.
+  Brightness is deliberately ignored (a dim red bulb still reads red); off,
+  white-only and unavailable lights look as before. (Pure `lightColorOf`.)
+- **Emergencies pulse red**: leak / smoke / gas / CO / safety / tamper / problem
+  binary sensors and sirens in `on` get a red pulsing ring over any display mode.
+  `unavailable`/`unknown` never alarm — an outage is not a fire. Honours
+  `prefers-reduced-motion`. (Pure `isAlarmState`.)
+
+## v1.26.0 — 2026-07-21 (state-reflecting icons + value display; issue #3)
+- **Auto icons now reflect live state**, like core HA: door/window/garage sensors
+  swap open↔closed variants, locks show locked/unlocked, a bulb lights up as
+  `lightbulb-on`. Conservative by design: only well-known pairs, never when the
+  user picked a custom icon, and `unavailable`/`unknown` keep the base icon.
+  Gated by the existing "live states" card option. (Pure `stateIcon`, unit-tested.)
+- **New marker display mode "Value instead of an icon"**: the measurement itself
+  (temperature °, humidity %, or any numeric state with its unit) becomes the
+  marker body — the small corner badges disappear for such markers. Direct
+  request from issue #3. Non-numeric entities fall back to the icon.
+
+## v1.25.0 — 2026-07-21 (three interaction modes: View / Plan / Devices)
+The approved UX redesign (docs/UX-MODES.md), confirmed by user feedback (#3):
+
+- **View** (default, and the only mode after every load): display and device
+  interaction only — tap/long-press/tooltips/pan/zoom. Nothing can be dragged or
+  edited; panning may start on top of an icon and never displaces it. The header
+  carries only space tabs, the counter, zoom and the mode switcher.
+- **Plan**: everything about geometry and appearance — room outline/delete/merge/
+  split tools, openings (placement, drag along walls, click-to-edit), room-label
+  dragging, per-space gear dialog, add space, the ⚙ fill palette. Orange stage frame.
+- **Devices**: marker work — icon dragging lives ONLY here, a click opens the
+  editor directly; add device, show-all curation, reset layout, icon rules. Accent frame.
+- The mode switcher is a segmented control shown to administrators; the standalone
+  markup toggle button is gone, "drag anywhere" (v1.9) is consciously reversed,
+  and the v1.23.1 view-mode opening drag/double-click moved into Plan.
+
+## v1.24.2 — 2026-07-16 (lights fill: a color for rooms with no light sources)
+- The "Fill: lights" group in General settings gained a third color — **"No light
+  sources"**. Its default opacity is 0, so rooms without any lights stay unfilled
+  exactly as before; give it an opacity and such rooms get their own tint,
+  distinguishable from "all lights off".
+
+## v1.24.1 — 2026-07-16 (space tab: gear instead of pencil)
+- The small icon next to a space name in the tabs is now a gear (was a pencil) —
+  the dialog it opens is space *settings* (plan, display, scale), not just renaming.
+
+## v1.24.0 — 2026-07-16 (general settings: fill palette; per-space LQI toggle)
+- **New "General settings" dialog** (⚙ in the header): the fill colors used by every
+  space, grouped by mode — lights (on / all off), temperature (cold / comfortable /
+  hot) and zigbee signal (weak / strong endpoints of the gradient). Every color has
+  its **own opacity slider**; the zigbee fill interpolates between the two configured
+  endpoint colors. Stored server-side in `settings.fill_colors` (defaults are not
+  persisted); the static `houseplan-space-card` uses the same palette.
+- **Per-space "Show zigbee signal (LQI)" toggle** in the space dialog: hides or shows
+  the LQI badges next to zigbee devices (and the signal line in room tooltips) for
+  that space; when never touched, the card-level `show_signal` option applies as before.
+- Fill opacity is now governed by the per-color setting; the space "Opacity" slider
+  keeps controlling borders and names.
+- New pure helpers `fillColorsOf` / `lerpColor` / `roomFillStyle` (+4 tests: 77 → 81);
+  backend schema for `fill_colors` and `show_lqi`; smoke `smoke_general_settings`.
+
+## v1.23.2 — 2026-07-16 (manual upload limit raised to 50 MB)
+- The per-file limit for attached manuals (PDF etc.) is now **50 MB** (was 25).
+  The limit is still enforced while the multipart body streams in, so an oversized
+  upload is cut off early rather than buffered whole; the error toast reads the
+  actual limit from the server response.
+
+## v1.23.1 — 2026-07-17 (openings: hover, drag along walls, double-click properties)
+- **Hover affordance**: an accent outline hugs the opening's wall strip on hover, with a
+  grab cursor — placed openings now look grabbable.
+- **Drag along walls** (view mode): an opening re-snaps continuously to the nearest derived
+  wall while dragged; too far from any wall → it stays put. `snapToWall` now normalizes the
+  angle to [-90, 90) — two rooms share a wall with OPPOSITE edge directions, and without this
+  a drag across segment boundaries flipped the hinge side back and forth. Saved on release.
+- **Click / double click**: a single click still opens the status card (now via a 250 ms
+  timer); a **double click opens the properties dialog** right from view mode. The markup
+  "Opening" tool behaves as before. Hit zone made slightly thicker and is now a strip along
+  the wall (previously it covered the whole swing square, causing accidental hovers).
+- (+1 test: 76 → 77.)
+
+## v1.23.0 — 2026-07-17 (doors & windows with live open/lock state)
+Visual language after easy-floorplan (MIT); the placement model is ours.
+- **New markup tool "Opening"**: click next to a wall → the opening snaps onto the nearest
+  DERIVED room wall (walls have no independent existence — v1.19.0) and takes its angle, then a
+  dialog asks for type (door/window), **length in real cm** (defaults: door 90, window 120 —
+  the per-space scale makes this honest), an open/close sensor (door/window-class
+  `binary_sensor`/`cover`, invertible) and, for doors, a **lock entity**. The opening keeps
+  absolute coordinates, so editing/merging/deleting rooms never breaks it. Click an existing
+  opening with the tool to edit or delete it.
+- **Live rendering**: a door is a leaf hinged at the jamb with a quarter-circle swing arc that
+  "draws on" (stroke-dashoffset) as it opens; a window is two casement leaves meeting in the
+  middle. Открыто → the moving parts take the accent colour and animate (CSS transitions,
+  `prefers-reduced-motion` honoured). No sensor → the classic static plan: doors drawn open,
+  windows closed. `unavailable`/`unknown` freeze that default — an outage must not fake motion
+  (pure `openingAmount`, unit-tested). Hinge side / swing side via flip toggles.
+- **Locks**: a padlock badge beside the door — green closed when `locked`, orange open when
+  unlocked, grey question when unknown. The lock is NEVER toggled from the plan (the card's
+  standing security rule); clicking the opening or the badge shows an **info card** with both
+  states.
+- New pure helpers `snapToWall` (projection + wall angle over derived edges) and
+  `openingAmount`; `space.openings[]` validated server-side. (+2 tests: 74 → 76.)
+
+## v1.22.0 — 2026-07-17 (presence ripples, per-device icon size/rotation, one-click install)
+Ideas borrowed from [easy-floorplan](https://github.com/nicosandller/easy-floorplan) — the visuals,
+not the model.
+- **Presence ripples**: `display: badge | ripple | icon_ripple` per marker, with `ripple_color`
+  and `ripple_size`. Active → pulsing rings; idle → a faint dot. Gated by the pure
+  `isActiveState` — independent of the card-wide live_states toggle, and `unavailable`/`unknown`
+  count as idle so an outage never leaves a ring pulsing. Honours `prefers-reduced-motion`.
+- **Per-device icon `size` (×0.5–3) and `angle`** — sizing now hangs off `--dev-size`, so value
+  badges scale with the device.
+- **One-click install badge** (My Home Assistant → HACS) in both READMEs.
+- (+1 test.)
+
+## v1.21.3 — 2026-07-16 (room labels: no text shadow)
+- Room name labels no longer carry a text shadow — crisper look on both the white
+  hand-drawn canvas and plan images.
+
+## v1.21.2 — 2026-07-16 (space-dialog polish)
+- The **"Scale (cm per cell)" input is compact** again — a generic `width:100%`
+  dialog rule was stretching it across the row.
+- **A space with no background image now gets a white "paper" canvas** instead of
+  the dark stage, so hand-drawn rooms read like a floor plan on paper.
+
+## v1.21.1 — 2026-07-16 (audit: split snaps to the wall, docs for merge/split)
+- **Fix (found in audit):** Split required each click to land on a grid node, so it
+  silently refused rooms whose walls are not grid-aligned (imported or older polygons)
+  — the "pick a wall" toast fired no matter where you clicked. The click now snaps to
+  the room's nearest wall (`closestPointOnBoundary`) instead of the grid, with the pull
+  capped at ~6 grid cells so an accidental click in the middle of a room stays a miss
+  rather than becoming a wall point the user never meant; `splitRoom()` still rejects
+  a cut that is not a clean wall-to-wall chord. Also makes aiming easier on the fine
+  (240-cell) grid.
+- **Docs:** README (en + ru) now documents room Merge, Split, the drawing ruler and the
+  per-space scale — these v1.18–v1.21 features were shipped without user-facing docs.
+  `docs/TESTING.md` gained merge/split rows and a fresh self-run record.
+- New smokes `demo/smoke_merge_split.mjs` and `smoke_split_nonsnap.mjs`;
+  `closestPointOnBoundary` unit-tested. (+1 test: 72 → 73.)
+
+## v1.21.0 — 2026-07-16 (merge and split rooms)
+- **Merge** (toolbar "Merge"): click a room, then a neighbour. Only rooms that **share a wall**
+  can merge — and that is decided by the result rather than a heuristic: `mergeRooms` unions the
+  outlines and accepts the pair only when they collapse into ONE hole-free outline. A corner
+  touch, rooms apart, or a union enclosing a hole are refused. A dialog picks which name and
+  area survive; the kept room keeps its id, so its label position and devices stay put. The
+  dialog warns that the other area is released.
+- **Split** (toolbar "Split"): click the room, then two points on its walls — the chord cuts it
+  in two, with the live ruler on the cut. **The bigger part stays the room it was** (name, area,
+  devices); the smaller becomes a new room and its dialog asks for name/area. Cancelling the
+  dialog leaves the room whole — the cut is applied only on confirm. Cuts that do not run
+  wall-to-wall inside the room (ends off the wall, chord leaving a concave room, a chord along a
+  wall) are refused.
+- Boolean geometry via **polyclip-ts** (proper ESM + native types; `polygon-clipping` ships named
+  types but a default-only ESM build, which breaks either tsc or the runtime). Verified against
+  the real plan, where neighbouring walls overlap collinearly instead of matching exactly —
+  the case a hand-rolled union gets wrong. Bundle: 151 KB → 202 KB.
+- New pure helpers: `polygonArea`, `mergeRooms`, `splitRoom`. (+5 tests: 67 → 72.)
+
+## v1.20.0 — 2026-07-16 (rooms may not overlap)
+- **A click strictly inside an existing room is refused** while drawing (toast names the room).
+  Being *on* a wall stays legal — neighbouring rooms share walls, and real walls overlap
+  collinearly rather than match exactly, so new vertices land on existing outlines mid-span
+  all the time. `pointStrictlyInside` excludes the boundary explicitly (ray casting alone is
+  unreliable exactly on an edge).
+- **Closing an outline that overlaps an existing room is refused** — vertex checks alone are not
+  enough: an outline drawn *around* a room has every vertex outside it. The outline stays open
+  so it can be corrected. Nesting one room inside another counts as an overlap.
+- New pure geometry in logic.ts: `roomPoly`, `pointOnBoundary`, `pointStrictlyInside`,
+  `segmentsProperlyCross` (touching/collinear is deliberately not a crossing), `roomsOverlap`
+  (edge crossings + containment probe, which also catches duplicate outlines). (+4 tests: 63 → 67.)
+
+## v1.19.0 — 2026-07-16 (a line is never a thing of its own)
+**Model change.** A wall can only exist as an edge of a closed room. Consequences:
+- **Walls are derived from room outlines** (`roomEdges` in logic.ts), not stored. A wall
+  shared by two rooms is emitted once, so **deleting a room keeps the borders its neighbours
+  still contribute** — and drops the walls nobody else uses. This falls out of the model
+  instead of needing bookkeeping.
+- **An abandoned outline leaves nothing behind.** Previously every click pair was written to
+  `space.segments` immediately, so a contour you never closed left orphan lines on the plan.
+  Now nothing is persisted until the room is saved.
+- **The "Erase line" tool is gone** — there is no standalone line to erase. Mis-clicks are
+  undone with Esc / Ctrl+Z as before.
+- **`space.segments` is dropped on every save** (legacy configs shed it on first write).
+  Validation still tolerates the field so a stale browser tab cannot fail a save; diagnostics
+  no longer reports it. Lines that belonged to no room disappear on upgrade — by design.
+- Dead code removed: `_addSegment`, `_removeSegmentByKey`, `_distToSeg`, `_pathSegs`, `_segKey`.
+  `segKey(a, b, prec)` gained a precision argument (normalized coords need more than render
+  units). (+2 tests: 61 → 63.)
+
+## v1.18.1 — 2026-07-16 (fix: the drawing ruler was invisible)
+- Fix on top of v1.18.0: the length badge never showed up while drawing. It was rendered
+  inside `.devlayer`, and `.stage.markup .devlayer { display: none }` hides that whole layer
+  in markup mode (so icons do not get in the way) — the badge was in the DOM but invisible.
+  It now lives in its own `.measurelayer` (absolute, `pointer-events: none`), which markup
+  mode does not hide. Verified visually on a real drawn segment ("3.60 m" on screen).
+- Testing lesson (see docs/TESTING.md): asserting on `textContent` is not enough — a DOM
+  query passes on elements hidden by an ancestor. Check `offsetParent`/rect or look at a
+  screenshot.
+
+## v1.18.0 — 2026-07-14 (live measurements while drawing rooms + per-space scale)
+- **Ruler while drawing.** In room-markup "draw" mode, a badge follows the cursor showing the
+  length of the current segment (last placed vertex → cursor). Units come from the HA unit
+  system: metric → metres ("1.25 m"), imperial → feet+inches ("4′ 1″").
+- **Per-space scale.** New "Scale (grid cell size)" field in the space dialog — cm represented
+  by one grid cell (default **5 cm**, i.e. 240 cells ≈ 12 m). Stored as `space.cell_cm`; each
+  plan can have its own real-world size.
+- Pure helpers `segmentCm` / `formatLength` in logic.ts (unit-tested); `_fmtLen` +
+  `_renderMeasureLabel` in the card; `.measurelabel` style; i18n `space.scale_label`/`scale_unit`.
+  (+3 tests: 58 → 61 frontend.)
+
 ## v1.17.2 — 2026-07-11 (humidity badge: gate on the sensor, not the icon)
 - Fix on top of v1.17.1: the humidity `%` badge is now shown whenever the marker's primary

+## Dependency and cache gotchas
+
+- **polygon-clipping is a trap**: its `.d.ts` declares named exports but the ESM build has only

+# UX redesign: three modes (approved 2026-07-21)
+
+> Approved design for reorganizing all card interactions into three tab-like modes.
+> Driven by the owner's mandate and confirmed by real user feedback
+> ([issue #3](https://github.com/Matysh/houseplan-card/issues/3): *"When moving the
+> map around, I sometimes move the doors/sensors around"*). This document is the
+> source of truth for the implementation iterations below. No code has been changed yet.
+
+## Principle
+
+A segmented control in the card header with three tabs; the active one is visually
+highlighted, and edit modes add a colored frame around the stage so the mode is
+obvious at a glance:
+
+**[ 👁 View ] [ 📐 Plan ] [ 🔧 Devices ]**
+
+- **View** is the default and the only mode after every load (edit modes are never
+  restored across reloads).
+- **Plan** and **Devices** are shown only to admins when `admin_only` is on.
+
+## View — display and device interaction only
+
+Allowed: pan/zoom (wheel, pinch, buttons), switching spaces, device tap
+(info / more-info / toggle per settings), long-press → info card, opening tap →
+door/lock info card, room tap → HA area, hover tooltips (name, temperature, signal).
+
+Removed from this mode (they move, not die):
+- icon dragging ("drag anywhere", v1.9 — consciously reversed),
+- room-label dragging,
+- opening dragging along walls and double-click properties (v1.23.1),
+- every edit button in the header (+device, 👁 show-all, ↺ reset, ⬡ rules, ⚙ general,
+  per-space gear, markup toggle).
+
+Header in View: space tabs, device count, zoom cluster. Nothing else.
+
+## Plan — geometry and appearance of the space
+
+- Toolbar tools: Outline room, Delete room, Merge, Split, Opening (place / drag along
+  walls / properties), Room labels (drag positions — labels are part of the plan).
+- Space gear dialog (title, plan image / hand-drawn, scale, Display section, show_lqi),
+  add space, floors import, delete space.
+- ⚙ General settings (fill palette) lives here — it is about the plan's appearance.
+
+## Devices — placement and marker configuration
+
+- Icon dragging (ONLY here). Click on a device opens the **edit dialog directly**
+  (binding, name, icon, size/angle, display badge/ripple + colors, tap override,
+  model/link/description/PDFs, room).
+- + add device/entity/virtual, hide device, ↺ reset layout, 👁 show-all (curation
+  tool), ⬡ icon rules.
+
+## Deprecations decided
+
+1. "Drag anywhere" (v1.9) — reversed by this design.
+2. Opening drag / dbl-click properties in view (v1.23.1) — moved into Plan.
+3. The markup toggle button — replaced by the Plan tab.
+4. Legacy localStorage mode (card without the integration) — candidate for removal
+   in the next major; adds branching for a half-working scenario.
+
+## Approved follow-up features (from issue #3, by priority)
+
+1. State-reflecting icons (open/closed door variants etc., like core HA).
+2. `display: value` — show the measurement instead of an icon.
+3. Light color in the icon/ripple (RGB lights).
+4. Alarm visual (leak/smoke/doorbell): red pulse overlay.
+5. Rooms as sub-areas without an HA area + manual device placement by room id.
+6. Backlog (not planned): music notes for players, directional TV ripples.
+
+## Implementation iterations
+
+- **It.1 — mode shell:** the segmented control, mode state, View-mode gating of all
+  edit interactions/buttons (biggest UX win, smallest surface).
+- **It.2 — Plan tab:** move markup tools + space dialogs + labels drag + openings
+  editing under Plan; colored frame indicator.
+- **It.3 — Devices tab:** drag + direct-edit click + curation tools under Devices.
+- **It.4+:** follow-up features 1–5 above, each its own release.

Matysh	961d6afe67	fix v1.28.1: openings fully inert in View mode - op-hit: pointer-events none + default cursor by default; interactive (grab, hover outline, drag) only inside Plan; lock badge is a pure indicator - opening click edits in Plan with any tool; no interaction whatsoever in View - smoke_inert_openings.mjs; TESTING.md updated	2026-07-22 10:34:03 +03:00
Matysh	b9fecbdd95	Merge subarea-rooms: manual placement without an HA area v1.28.0	2026-07-22 10:27:31 +03:00
Matysh	9fd36bd710	feat v1.28.0: sub-area rooms — manual device placement without an HA area (issue #3 ) - area-less rooms appear in the marker room list ('no area, manual'); markers store room_id and land at the room centre; dialog reopen restores the choice - pure parseRoomRef (space#area / space#@roomId) + unit tests; backend schema - ROADMAP phase 11 closed; TESTING.md row; smoke_subarea.mjs	2026-07-22 10:25:20 +03:00
Matysh	a9346c9c14	Merge rgb-alarm: RGB light colors + alarm pulse v1.27.0	2026-07-22 10:23:15 +03:00
Matysh	794b02b84f	feat v1.27.0: RGB light colors + red alarm pulse (issue #3 ) - lightColorOf(): on+rgb_color tints icon/glow/ripple (explicit ripple color wins); brightness ignored by design; off/white/unavailable unchanged - isAlarmState(): leak/smoke/gas/CO/safety/tamper/problem sensors and sirens in 'on' pulse a red ring over any display mode; outages never alarm; prefers-reduced-motion honoured - +2 unit tests, smoke_rgb_alarm.mjs, TESTING.md rows	2026-07-22 10:21:08 +03:00
Matysh	3bc25ad5ae	Merge state-icons: state-reflecting icons + value display v1.26.0	2026-07-22 10:19:42 +03:00
Matysh	d1a79cd0b4	feat v1.26.0: state-reflecting icons + 'value instead of an icon' display (issue #3 ) - stateIcon(): door/window/garage open-closed, lock locked-unlocked, bulb on; custom icons and unavailable/unknown never morph; gated by live_states - marker display 'value': the measurement (with unit) is the marker body, corner badges hidden; numeric fallback chain temp - hum - primary state - TESTING.md rows, smoke_state_value.mjs, +1 unit test	2026-07-22 10:17:32 +03:00
Matysh	5522399a3a	Merge ux-modes: three interaction modes v1.25.0	2026-07-22 10:13:08 +03:00
Matysh	185604396d	feat v1.25.0: three interaction modes — View / Plan / Devices (docs/UX-MODES.md) - View (always the default): display + device interaction only; no dragging of icons/labels/openings; panning can start on an icon; clean header - Plan: markup tools, openings editing (click-to-edit, drag along walls), label drag, space dialogs, fill palette; orange frame; icons hidden but labels visible - Devices: icon drag only here, click opens the marker editor directly; add/ show-all/reset/rules buttons; accent frame - segmented mode control (admins only); removed: markup toggle button, view-mode opening drag/dblclick (v1.23.1), 'drag anywhere' (v1.9 reversed) - README en+ru updated; TESTING.md Modes section; smoke_modes.mjs	2026-07-22 10:11:02 +03:00
Matysh	9d0e2cab00	docs: approved UX-modes design (View/Plan/Devices tabs) — docs/UX-MODES.md + ROADMAP phase 11 Research only, no product changes. Confirms and structures the owner's mandate (view mode must be display-only) and issue #3 feedback; lists deprecations and approved follow-up features with implementation iterations.	2026-07-22 10:02:55 +03:00
Matysh	73f176ea2f	Merge light-none: 'no light sources' fill color v1.24.2	2026-07-22 09:40:05 +03:00
Matysh	b7599c642c	feat v1.24.2: 'no light sources' color in the lights fill group Default opacity 0 preserves the historical no-fill behavior; assigning an opacity tints lightless rooms distinguishably from 'all lights off'.	2026-07-22 09:38:05 +03:00
Matysh	4ec7e7081f	Merge tab-gear: gear icon on space tabs v1.24.1	2026-07-22 09:35:34 +03:00
Matysh	ee5f65752a	style v1.24.1: gear instead of pencil on space tabs (the dialog is settings, not renaming)	2026-07-22 09:33:32 +03:00
Matysh	574d3b8f9a	Merge general-settings: global fill palette + per-space LQI toggle v1.24.0	2026-07-22 09:30:38 +03:00
Matysh	90c558eee7	feat v1.24.0: general settings (global fill palette) + per-space LQI toggle - General settings dialog: fill colors grouped by mode (light on/off, temp cold/ok/hot, lqi weak/strong), each with its own opacity; lqi fill lerps between the endpoints; stored in settings.fill_colors (defaults omitted); space-card uses the same palette - per-space show_lqi toggle (badges + room tooltip line), inherits the card's show_signal when unset - fillColorsOf/lerpColor/roomFillStyle helpers (+4 tests), backend schemas, smoke_general_settings; TESTING.md updated in the same commit	2026-07-22 09:28:38 +03:00

Matysh	1fa6c6cdee	feat v1.23.2: raise the manual-upload limit to 50 MB MAX_FILE_BYTES 25→50 MB (still enforced while the multipart body streams in); frontend fallback in the error toast updated; TESTING.md row updated.	2026-07-21 08:02:53 +03:00
Matysh	70d3453f78	docs: catch all documentation up to v1.23.1 Validate / hacs (push) Has been cancelled Details Validate / hassfest (push) Has been cancelled Details Validate / frontend (push) Has been cancelled Details Validate / backend (push) Has been cancelled Details - READMEs (en+ru): doors/windows/locks section (openings tool, live rendering, drag, double-click properties), presence ripples + per-device icon size/rotation in the manual-marker section. - ARCHITECTURE: room geometry rules (derived walls, no-overlap, merge/split via polyclip-ts and why not polygon-clipping), doors & windows model (space.openings, snapToWall, absolute coords, security), per-marker display fields + cell_cm ruler. - DEVELOPMENT: gotchas — polygon-clipping ESM/types mismatch; same-version redeploys keep ?v so browsers cache the old bundle. - STATUS: snapshot refreshed (releases to v1.23.1, dacha deployed v1.23.1), milestones v1.17–v1.23.1 incl. the lost-sources lesson (push right after building). - ROADMAP: 8 shipped Quality-Scale items ticked (done since v1.12.0). - TESTING: restored the v1.22.0 ripple checklist lost in the sandbox reset.	2026-07-17 07:53:16 +03:00
Matysh	3e53b012be	feat v1.23.1: openings — hover outline, drag along walls, double-click properties - Hover: an accent outline hugs the opening's wall strip + grab cursor. - Drag (view mode): re-snaps continuously to the nearest derived wall; snapToWall now normalizes the angle to [-90,90) — neighbouring rooms yield the same wall in opposite directions, which used to flip the hinge while dragging across segment boundaries. setPointerCapture wrapped in try/catch (an inactive pointerId must not kill the drag). - Click still opens the status card (via a 250ms timer); double click opens the properties dialog from view mode. Hit zone is now a slightly thicker strip along the wall instead of the whole swing square (fewer accidental hovers). +1 test (77). Verified live: drag moved a test door exactly along a vertical wall (angle 90 -> -90), click/dblclick/markup-tool paths all работают; the user's 12 real openings untouched.	2026-07-17 07:43:10 +03:00
Matysh	ff7c1b883c	feat v1.23.0: doors & windows with live open/lock state New markup tool 'Opening': click a wall — the opening snaps onto the nearest DERIVED room wall (v1.19.0 model: openings keep absolute coords, so room edits never break them) and takes its angle. Dialog: type, length in real cm (door 90 / window 120 — per-space scale makes it honest), contact sensor (invertible), lock (doors). Rendering after easy-floorplan (MIT): hinged leaf + swing arc drawing on via stroke-dashoffset; window = two casements. No sensor → static plan defaults (door open, window closed); unavailable freezes the default (pure openingAmount, tested). Lock: padlock badge (green locked / orange unlocked / grey unknown); the lock is never toggled from the plan — clicking shows an info card with both states. snapToWall + openingAmount in logic.ts; space.openings validated server-side. +2 tests (76). Verified live on the dacha (real TTLock + TRV window sensor).	2026-07-17 07:21:20 +03:00
Matysh	7c9731655e	feat v1.22.0: presence ripples, per-device icon size/rotation, one-click HACS badge Visuals borrowed from easy-floorplan (github.com/nicosandller/easy-floorplan), model kept ours. isActiveState is independent of the live_states toggle; unavailable/unknown count as idle. Honours prefers-reduced-motion. Badges scale with --dev-size. +1 test (74).	2026-07-17 07:02:22 +03:00

Matysh	ae10befd58	fix v1.21.2: space-dialog polish - scale (cm/cell) input compact again (generic width:100% dialog rule stretched it) - space with no background image gets a white paper canvas (.stage.noplan), so hand-drawn rooms read like a plan on paper - TESTING.md updated in the same commit	2026-07-16 14:32:07 +03:00

Matysh	9288d74f6f	fix+docs v1.21.1: audit of v1.16-v1.21 - fix: Split snaps the click to the room's nearest wall instead of the grid, so it works on non-grid-aligned rooms (imported/legacy polygons); the pull is capped (~6 cells) so accidental mid-room clicks stay a miss; splitRoom() still rejects a bad cut. closestPointOnBoundary() + unit test. - docs: README (en+ru) documents Merge/Split/ruler/per-space scale (were undocumented); TESTING.md merge/split rows + fresh self-run; new smokes smoke_merge_split, smoke_split_nonsnap (incl. the capped-pull case). - 73 frontend + 12 backend tests green; module eval + both cards register.	2026-07-16 11:43:15 +03:00
Matysh	b706ad4b49	feat v1.21.0: merge and split rooms - Merge: click a room, then a neighbour. Adjacency is decided by the RESULT, not a heuristic: mergeRooms unions the outlines and accepts only when they collapse into one hole-free outline (corner touch / apart / hole => refused). A dialog picks the surviving name+area; the kept room keeps its id so its label and devices stay put. - Split: click the room, then two wall points; the chord cuts it, live ruler on the cut. The bigger part stays the room (name/area/devices), the smaller opens the new-room dialog. The cut is applied only on confirm — Cancel leaves the room whole. - Boolean geometry via polyclip-ts (proper ESM + native types; polygon-clipping ships named types but a default-only ESM build, breaking either tsc or the runtime). Verified on the real plan, where neighbouring walls overlap collinearly rather than match exactly — the case a hand-rolled union gets wrong. Bundle 151->202 KB. +5 tests (72). Verified live: merge of Сауна+с/у -> 4-vertex outline, non-adjacent refused, split preserves area (26667 -> 13333+13333), cancel leaves the room whole.	2026-07-16 08:10:24 +03:00
Matysh	1552bff99a	feat v1.20.0: rooms may not overlap - A click strictly inside an existing room is refused while drawing; a click ON a wall stays legal (neighbours share walls, and real walls overlap collinearly rather than match exactly, so vertices land on existing outlines mid-span constantly). - Closing an outline that overlaps an existing room is refused — vertex checks alone are not enough, an outline drawn AROUND a room has every vertex outside it. Nesting counts as overlap. The outline stays open so it can be corrected. - New pure geometry: roomPoly, pointOnBoundary, pointStrictlyInside, segmentsProperlyCross (touching/collinear deliberately not a crossing), roomsOverlap. +4 tests (67). Verified live: all 15 existing neighbour pairs stay clean (no false positives).	2026-07-16 07:59:01 +03:00
Matysh	65268a7985	feat v1.19.0: a line is never an entity of its own — walls are derived from rooms A wall can only exist as an edge of a closed room: - roomEdges(rooms) derives walls from room outlines, deduping shared ones, so deleting a room keeps the borders its neighbours still contribute and drops the rest — the rule falls out of the model instead of needing bookkeeping. - Nothing is persisted while drawing: an outline you never close leaves no lines behind (previously every click pair was written to space.segments immediately). - The 'Erase line' tool is gone; space.segments is stripped on every save (validation still tolerates it on read so a stale tab cannot fail a save). - Dead code out: _addSegment/_removeSegmentByKey/_distToSeg/_pathSegs/_segKey. Docs (ARCHITECTURE/TESTING/CHANGELOG) updated in the same commit. +2 tests (63).	2026-07-16 07:27:23 +03:00
Matysh	4593d96955	fix v1.18.1: the drawing ruler badge was invisible — .stage.markup hides .devlayer The v1.18.0 measure label was rendered inside .devlayer, which markup mode hides entirely (display:none) so icons don't obstruct drawing. Moved it to its own .measurelayer. Verified visually on a real segment (3.60 m).	2026-07-16 06:53:31 +03:00

New pure helpers segmentCm/formatLength (unit-tested). - New per-space 'Scale (grid cell size)' field (space.cell_cm, default 5 cm) so each plan has its own real-world dimensions. i18n en/ru, .measurelabel style. +3 tests (61).	2026-07-14 18:48:56 +03:00
