Stage 5 of #780.
- Import summary: «Strips left unbound after import: {n}» from the backend
`unbound_led_strips` count; «Optimize plans» reports strips passing
through walls per space and edits none (AC16).
- Linear field for long strips (ТЗ §13.2): pieces of at most the radius
along the polyline, emitters thinned to r/4, each piece clipped to the
visibility fans of its own emitters as separate clipPath children (no
boolean pass per piece), one floor clip for the whole layer, no fan at
all where nothing blocks within the radius; a grid index of body faces
and boxed inside tests; unchanged fields skip re-diffing. 50×50 on the
large house: first stable frame ~1.4 s, warm space ~1.1 s locally.
- led-strips-v1 profile: demo/benchmark_led_strips.mjs with the derived
large-house fixture (10×5, 50×50, none), absolute limits of the ТЗ table
in demo/performance/budgets-led-strips.json, exact counters (zero
recomputes on HA ticks/camera/colour, ≤50 cache entries, no growth over
20 cycles); added to the full performance workflow.
- Bundle: LAZY_LED_GZIP_CEILING 10 KiB, LAZY_LED_EDITOR_GZIP_CEILING 11 KiB
(measured + 10 %, rounded up); overlaps with the initial and editor
graphs refused; the lazy editor graph stays inside its ceiling.
- Smokes smoke_led_strip_draw/bind/glow, linked in smoke-links; 13 mutants
in the registry (7 browser guards in the inventory); config field registry
entry `spaces[].led_strips`.
- Golden: five new scenes on the `golden-led` space of the visual fixture
(`ledStrips` option, the designer's four strips on #868D94), matrix v71.
- Docs: LIGHT, DEVICE-PRESENTATION, USER-GUIDE (en/ru), UX-MODES,
ARCHITECTURE, ISOMETRIC, CONFIG-COMPATIBILITY, TOUCH-SUPPORT, demo/stand
README, performance README; docs/design/led-strips with the unchanged
designer archive, two paired frames and ACCEPTANCE.md; both changelogs.
