tools/aseprite/maps/ holds the source of truth: char-grid pixel maps + shared palette for five _ph placeholder sprites (M03 32px per MOE.md design law cues — round silhouette, mismatched eyes, bolted hardpoint, pillar feet; grunt 16px untagged olive; burster 20px HEAT glow band; KINETIC slug; scrap diamond). Two interchangeable renderers: gen_sprites.lua (aseprite -b, emits .aseprite + .png — run on any machine with Aseprite) and preview.py (Pillow, identical PNGs headless + nearest-neighbor zoom for review). Outputs gitignored; greybox scenes untouched — art stays out of the game per the greybox rule.

Same source of truth as gen_sprites.lua (tools/aseprite/maps/); use

this for headless preview on boxes with no Aseprite. Output is
