A floor switch replaces the whole stage, so the card's pointer-hover
MutationObserver receives hundreds of records whose targets are the same
few containers. Each record re-ran `matches` and a `.devlayer` subtree
`querySelector` on its target, and kept doing so after the device layer
had already been found. The batch logic moves to `deviceLayerMutated` in
device-hit-owner.ts: a node is checked at most once per batch, the first
hit ends the checks, and every added node still goes through
`_syncPointerHoverSubtree` in record order. The card shrinks by 12 lines.
The View stair layer read the card's `_model` getter once more for every
navigable stair; the getter rebuilds the config fingerprint on each read.
`renderLayer` now reads it once.
`languageRenderGate` wrote `lang` on the host on every render. It now
writes it only when the value differs (language switch, English fallback,
a foreign value); an unchanged value is left alone.
No behaviour changes: DOM, tooltips and pixels are the same. Unit tests
count subtree queries per node, `_model` reads per render and `lang`
writes; one mutant per change restores the old behaviour.

The Plan editor rule `.hp-stair.input-enabled .hp-stair-hit { cursor: move }`
also matched the View layer, which sets input-enabled only to receive
clicks. The hit area sits over the outline, so the link's pointer on the
group was never visible and every stair in View showed a drag it cannot do.
- src/stairs-view.ts: View stairs carry `hp-stair-view`.
- plan.styles.ts: `move` applies only without it; in View the hit area
keeps the group's cursor — pointer on a link, the stage's otherwise.
- demo/smoke_stairs.mjs: computed cursors in View (link, no target) and
in the Plan editor; the two View checks are red on the old code.
- test/stairs.test.mjs: the cascade without Chromium; mutant
view-stair-cursor-move-again.
- docs/STAIRS.md, changelogs.

Путь чистого пола строят четыре места рендера, а площадь читают только
подсказка комнаты и PDF. cleanFloorForRoom больше не вычитает лестницы при
построении пути: площадь считается при первом чтении и хранится в том же
закэшированном объекте. geometryMinusStairs передаёт в polyclip только
контуры лестниц, чей габарит пересекает вычитаемую геометрию, — результат
тот же, а комната на этаже с 250 лестницами больше не прогоняет все 250.

Прямые и винтовые лестницы получили отдельную модель, инструменты редактора, безопасную межэтажную навигацию, вычитание из чистой площади и плоское отображение в 2.5D.
