nx_game_scaffold.nx

nx_game_scaffold.nx -- LIB: the SCAFFOLD that ties the universal Nishi-builder catalog (the parts SSOT) to the game ecosystem, HARDWARE-RUNG-UP, each rung building on the one below, up to AUTOGENERATION. The rungs: R0 catalog SSOT (nb_*) -> R1 parts (mechanic/entity/level/tilemap emitters) -> R2 COMPOSE (pick parts) -> R3 VALIDATE (all parts resolve, sovereign-safe) -> R4 RUN (ng_sim_run = the deterministic runtime) -> R5 RASTER (integer, NO FLOAT, packed-RGB framebuffer -> PNG, the ecosystem's sovereign visual standard) -> R6 AUTOGENERATE (procedurally synthesize NEW playable levels into the catalog, each verified by the runtime). This is the platformer genre rung of project-nishi-game-ecosystem-generative, sourced from the ONE universal catalog. Sovereign: NO float (decimals already milli-fixed in nx_game_render), NO JS, NO 3rd-party draw -- the raster is pure-Nishi integer pixels (reuses nx_shade + nx_png, the same chain the arcade/2048 rungs ship through). license_tier: ORIGINAL
