Run locally
node serve.js # http://localhost:8813
No build step. three.js (r170) and cannon-es are vendored in vendor/ (MIT), so it works fully offline.
Running locally also unlocks two extras that use a local Ollama model: FUSE invents combinations that aren't in the pre-made recipe book (/api/fuse), and the standalone KRILLDIVE can judge answers missing from its lists.
Offline
After one visit the whole site works with no internet (PC, iPad, phone — also as an installed home-screen app). sw.js precaches every file; regenerate it before each push with node tools/build-sw.mjs (the cache version is a content hash).
Layout
index.html / hub.js — the hub (today's results, streak, scorecard)shared/bp.js — back-to-hub button, daily numbering, per-device seeds, storage helpersgames/<game>/ — each game is a self-contained static pagetools/sync-krilldive.mjs — copies KRILLDIVE in from its own project and bundles its packstools/gen-fuse.mjs — generates FUSE recipes with a local LLM (resumable)
