- [`index.html`](index.html) — Page shell: markup for map info, time bar, score, settings dialog; pulls `index.css` and `index.js`.
- [`index.js`](index.js) — Connects to BS+ WebSocket, parses JSON events (`gameState`, `mapInfo`, `pause`, `resume`, `score`), updates DOM; optional BeatSaver API fetch for custom maps; reads/writes settings from URL hash.
- [`index.css`](index.css) — Layout, theming, visibility toggles driven by body classes and CSS variables from settings.
- [`types.d.ts`](types.d.ts) — JSDoc typedefs for BS+ payloads and events (editor/IDE hints only).
- [`jsconfig.json`](jsconfig.json) — JS project roots/path so editors resolve modules and `types.d.ts`.
- [`images/`](images/) — Cover fallback (`unknown.svg`), characteristic icons under `images/characteristic/` (filenames match BS+ characteristic strings).
- [`README.md`](README.md) — User-facing usage (hosted URL, OBS, local `file://`, BS+ module).
- [`dprint.json`](dprint.json) — Formatter config for the repo.
- [`.editorconfig`](.editorconfig) — Basic indent/charset rules for editors.

## Out of scope here

Beat Saber Plus itself (game mod) exposes the socket; this repo is only the HTML/CSS/JS client.
