1// nx_game_web_emit.nx -- NISHI GAME ECOSYSTEM, emitter rung 1: MECHANISTIC, spec-driven emission of a
2// self-contained PLAYABLE BROWSER game (canvas front-end + JS logic back-end), LLM-FREE at runtime. Same
3// "data spec in -> playable game out" autonomy as nx_game_emit, but targeting the browser (nishifamily.com)
4// instead of terminal ASCII, and parameterized so a DIFFERENT spec yields a DIFFERENT game = real
5// generation (not a hand-cloned title). This rung covers the ARCADE/ACTION collect-class; later rungs add
6// genre-classes (puzzle/tower-defence/turn-based/...) mapped from the ingested registry. The emitted JS is
7// single-quoted (no escaping) and authored BY this organ. 100% sovereign emit. license_tier: ORIGINAL
