- fence: split into two paint slots — panel (posts/base/infill, default charcoal)
and rail (cap, default wood-finewood27) — as separate meshes with userData.slotId.
Fix applyFenceUVs to continuous world-space 1 UV unit = 1 m (drop the per-part
min origin that broke tiling across parts). New generateFenceSlotGeometries.
- roof: real catalog defaults for the segment surfaces via getRoofMaterialArray
(the actual default path): wall/trim concrete-plate (matches walls), deck +
soffit soft-white, shingle terracotta; textures-off role escape hatch kept.
Align nodes getRoofMaterials no-parent fallback to match.
- stair: body slot default -> preset-lightgrey.
- (biome formatting normalization of the round-1 merged renderer files rides along.)

Stair exposes three paintable slots — treads / body / railing (railing only
when railingMode != none) — on node.slots. The 2-material-index body mesh
maps materialIndex 0->treads, 1->body via userData.slotIds; railing meshes
tag userData.slotId='railing'. Per-slot resolution layers over the viewer's
base body/railing materials only in textures-on mode: node.slots ref ->
legacy per-part field (preserved) -> declared default (treads wood-woodplank48,
body wood-woodfine2, railing metal-steel). A custom preview swaps the targeted
body material-array index and whole-mesh railing materials. Monochrome
unchanged. Stops using DEFAULT_STAIR_MATERIAL.
