Continuing the post-migration cleanup. After registry-driven kinds
absorbed selection chrome, action menus, and boundary editing through
`def.floorplanAffordances`, the legacy plumbing in `floorplan-panel.tsx`
was left mounted with empty inputs — another ~4k LoC of dead code.
Removed:
- `Editor2dFloorplanActionMenuLayer` mount + its 10 `selectedX
ActionMenuPosition` useMemos. All ten action menus computed positions
from empty entry arrays / null `selectedXEntry`, so the layer never
rendered anything. `FloorplanRegistryActionMenu` is the only mount left.
- Legacy handle layers: `FloorplanWallEndpointLayer`,
`FloorplanFenceEndpointLayer`, `FloorplanWallCurveHandleLayer`, and
the four `FloorplanPolygonHandleLayer` mounts for slab / slab-hole /
ceiling / ceiling-hole — all rendered from `wallEndpointHandles` /
`slabVertexHandles` / etc. which were empty after the registry took
over endpoint, curve, and polygon affordances.
- `FloorplanZoneLabelLayer` mount + component. Zone labels are now
emitted as `kind: 'text'` from `def.floorplan` on the zone kind.
- Dead handlers: every `handle*Select`, `handle*PointerDown`,
`handle*DoubleClick`, `handle*HoverChange`, `handleFloorplan*Hover
Enter`, `handleSelected*` (Move/Delete/Duplicate/AddHole/HoleMove/
HoleDelete/Curve for all 10 legacy kinds), `duplicateSelected*`,
`handleSelectedWallCurve`, `handleSlabVertex*`/`Midpoint*`/`Edge*`/
`Hole*` (same for ceiling and zone), `handleWallEndpointPointerDown`,
`handleFenceEndpointPointerDown`, `handleWallCurvePointerDown`,
`emitFloorplanNodeClick`, `syncDeleteHoveredId`,
`handleZoneLabelClick`, `hasDuplicatableFloorplanSelection`,
`handleDuplicateFloorplanSelection`, `FloorplanDuplicateHotkey` mount.
- Dead handle data: `wallEndpointHandles`, `fenceEndpointHandles`,
`wallCurveHandles`, `canCurveSelectedWall`, and all the
slab/slab-hole/ceiling/ceiling-hole/zone vertex+midpoint+edge handle
useMemos.
- Dead selection / measurement useMemos: `selectedItemEntry`,
`selectedOpeningEntry`, `selectedSpawnEntry`, `selectedFenceEntry`,
`selectedStairEntry`, `selectedRoofEntry`, `selectedElevatorEntry`,
`selectedWallEntry`, plus `selectedItemClearanceMeasurements` and
`movingOpeningPlacementMeasurements` (both 100-200 lines of math
that consumed the empty entries).
- Two dead `<FloorplanMeasurementsLayer>` mounts (clearance / opening
placement) — both fed by useMemos that returned `[]`.
- `<FloorplanZoneLayer>` mount — `visibleZonePolygons` is always empty.
Kept:
- `siteVertexHandles` / `siteMidpointHandles` + `<FloorplanPolygonHandle
Layer>` mount for site — site is the only kind not registry-driven.
- `FloorplanStairLayer` mount (preview-only, hover/click props swapped
for noop helpers since the preview isn't interactive).
- Stub `selectedSlabEntry` / `selectedCeilingEntry` / `selectedZoneEntry`
as `null` typed values so the remaining hole-editing fallback code
compiles. Those fallbacks themselves run as no-ops now and can be
torn down in a follow-up.
Floor-plan panel: 14,395 → 10,466 lines (-3,929). Cumulative reduction
vs `main`: 17,913 → 10,466 (-7,447 lines, ~42%).
