Layout (per design paper §11):
- Top toolbar with Mode buttons (Auto-Tile / Direct), Save, Erase,
Rotate, Help.
- Right Layers side-panel (8 rows, top-down draw order) as single
source of truth for visibility + active layer — replaces the old
left-edge layer chips.
- Bottom status bar.
State + actions:
- mode = "auto-tile" | "direct" (Tab toggles).
- cheatsheet_open modal toggle (I key, dimmed overlay + key/action
table).
- SPOREL_CI=1 auto-exits after 30 frames (matches vagrant pattern;
ci_frames in manifest is not engine-enforced for kind:"module").
Paint behaviour itself is unchanged from 0.1.0 — bottom palette + the
real Auto-Tile / Direct paint loops land in 0.2.0b/c/d.
deps: lib-core.maps 0.5.1 -> 0.5.2 (consumes set_vertex / get_vertex).
Required by the schema-v3 work in lib-core.maps. The map-editor
v0.1 stays on the legacy tiles[] path and continues to function
unchanged through the auto-upgrade v1->v2->v3 chain on load.
Full migration to v3's vertex-painting + override-UI lands in the
map-editor v0.2 slice
(sporel-meta/docs/superpowers/plans/2026-05-28-map-editor-blob-v2.md).

Other module manifests (spine-prototype, vagrant-skeleton, etc.) use
the short directory name as the id, not the long 'sporel-module-X'
form which is reserved for the Gitea slug. The mismatch caused the
launcher script (which exports SPOREL_MODULE=map-editor) to fail
with ENGINE_ERR_MODULE_NOT_FOUND.
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.
