work.map.json was still schema-v2 with the legacy fa_terrain_v1
atlas — neither has a `material` field on its layers, so the
renderer's vertex/blob path never fired and Auto-Tile painting had
no visible effect (the set_vertex writes landed but the renderer
fell back to the cell-tile path that doesn't consume them).
Migration:
- schema_version 2 -> 3
- size 4x4 -> 16x16 (room to paint)
- atlases: fa_terrain_v1 -> blob_rect_stone (S-V2E2-RM-Blob 14-slot
atlas from lib-asset.prototype-blob-geom)
- layers: surface + wall, both with "material": "blob_rect_stone";
vertices+overrides start empty (lib-core.maps lazy-allocates on
first set_vertex)
Manifest:
- asset_aliases: fa_terrain_v1 -> blob_rect_stone (lib-asset.
prototype-blob-geom)
- deps: drop prototype-fa-starter, add prototype-blob-geom 0.1.0
Empty launchable module with deps on lib-core.maps 0.4.0, render,
camera, input, and the fa_terrain_v1 asset alias. Renders the
default 4x4 empty work-map; interactive editing wired in
subsequent commits.
