Replaces the placeholder colour swatches with actual atlas sub-tex
draws via the new lib-core.maps 0.5.4 getters:
- atlas_diffuse_handle(atlas_idx) -> raylib Texture2D handle
- atlas_tile_uv(atlas_idx, slot) -> {x, y, w, h} or nil
Renders each slot 1..14 (lib slot 0..13) scaled to fit the swatch
rect with draw_sprite_transform. Falls back to the legacy colour
square + slot-number label when the atlas isn't loaded (headless,
material missing, etc.).
Drives off state.get_active_atlas() (defaults to 0 — fine for the
single-atlas work map; multi-atlas selector is a future slice).
Also bumps lib-core.maps dep 0.5.3 -> 0.5.4.
sporel-module-map-editor
Interactive map editor for v2 Sporel map files. Click-to-paint, vertical layer-chip overlay on the left edge, collapsible atlas+tile picker bottom-left.
Run
Default — edit the module's in-place work map:
bash scripts/run-map-editor.sh
With a target — copy a real map in, edit, copy back out:
bash scripts/run-map-editor.sh ~/Projects/Sporel/sporel-modules/spine-prototype/maps/demo.map.json
UI
- Layer chips (left edge, vertical): top-of-stack down.
Rfat top toggles roof-edit mode; the other eight chips select the active layer.- Left-click = set active layer (or toggle roof mode)
- Right-click = toggle layer visibility (Rf chip ignores right-click)
- Atlas + tile picker (bottom-left): collapsed chip shows the active tile. Click to expand; click again or outside to collapse.
- Status chip (bottom-right): current mouse-cell coordinate plus a
*when the map has unsaved changes.

Limitations (v0.1.0)
- Tile thumbnails in the picker render as gray placeholders with tile-IDs as text — lib-core.maps v0.4.0 does not expose per-tile UVs to Lua, so visual thumbnails are a v0.2.0 task.
- Atlas list in the picker is purely informational; if a map declares multiple atlases, the active atlas is set from
state.luadefaults at startup and cannot yet be switched via UI (v0.2.0 hit-tests inside the expanded picker). - Engine bindings
engine.render.draw_rect_linesandengine.render.draw_lineare not yet registered — active-chip borders, hidden-layer strikethroughs, and the entity-slot divider will trigger runtime errors when their code paths execute. Adding the bindings is a small engine-side follow-up. - No undo/redo, no multi-tile brush, no entity placement, no heightmap editing — see the design spec §1 for the full out-of-scope list.
