# Regenerate assets
Everything under `assets/` is generated **deterministically** by `tools/gen/` (Node built-ins
only — no install needed).
## Run
`npm run gen` (= `node tools/gen/index.mjs`)
## Rules
- **Deterministic:** same input → same bytes. A clean re-run should leave `git status`
unchanged unless a generator actually changed.
- **Don't hand-edit files in `assets/`** — they are outputs. Edit the generators instead:
`tools/gen/{px,characters,world,backgrounds,audio,index}.mjs`.
- To swap in **real** art/audio, drop files into `assets/` keeping the same filenames; if an
extension changes, update the path in the `ASSETS` map in `src/config.js` (single source of
truth).
- After regenerating, sanity-check with `npm run test:levels` (boots each level + screenshots
the themed art).
