- BG_STOPS: +10deg #e8ddcf (morning light), +30..90deg #ffffff; night half
of the scale untouched (-4 #131a28, -12..-90 #070c14)
- drawn-plan paper vs white sky: all paper shapes now sit in one
.hp-paperg group; in daynight mode the group gets a subtle
drop-shadow so the sheet contour stays readable at high sun
(static mode and night unaffected)
- pinned colors updated: test/sun.test.mjs, demo/smoke_sun.mjs;
smoke_bg_color paperUnderneath follows the .hp-paperg wrapper
- docs/SUN.md: explicit BG_STOPS table
- demo/shot_daynight.mjs: noon/sunset/night stills of the scale
Owner: the white backing must hug the ROOMS — an L-shaped house or detached
buildings grew a white square around the plan. Drawn plans now paper one
opaque shape per room (paperRoomShapes in logic.ts) in exactly the room's own
geometry — polygon points / rounded rect verbatim — so the union of the stack
is the paper: islands paint over their parent, open (virtual) boundaries
change nothing, and the scene bg_color / daynight sky reaches the exterior
walls, shows in the L's pocket and between buildings. Image plans keep the
backdrop-image rect (the canvas IS the paper). A live resize preview
(_rszPreview) feeds _renderCfg, so the paper moves WITH a dragged wall.
Static space-card follows the same contract. Paper is fill-only (stroke:none).
smoke_bg_color §11–13 rewritten: L-shaped + detached test rooms, paper-per-
room DOM checks, resize-preview wiring, pixel probes (acid in the pocket and
between buildings, none inside rooms); §13 injects the snapshot directly —
the module-level config-store cache made the old WS mock a no-op. Was 8 red
on the previous build, green now. docs/SUN.md + docs/TESTING.md contract
updated; unit test for paperRoomShapes.
Owner request 2026-08-03: bg_color (and the daynight sky) used to shine
through the plan itself — a hand-drawn plan's translucent room fills sat
directly on the scene colour, and a transparent backdrop image let it
through too. An opaque rect.hp-paper now sits under everything the plan
draws and hugs the plan's extents (the backdrop image rect, or the drawn
content bounds the opening view fits). Its colour is the pre-bg_color
canvas: white for drawn plans (.stage.noplan), the theme card background
under an image and on the static space-card. The daynight night keeps
dimming the plan via the zoomwrap brightness filter ONLY — the paper's
alpha never changes. The scene colour is visible strictly AROUND the
plan, in view/kiosk/editors and the static card alike.
smoke_bg_color grew the contract (sections 11–13): paper presence,
geometry and opacity in view/editors/night, the white drawn-plan paper,
the static card's paper, plus a pixel proof against an acid #ff00ff
background (screenshot → canvas: no acid admixture inside the plan, acid
right outside it). The suite fails on the previous build.
docs: SUN.md background contract + TESTING.md checklist item.
