**🎉 [Install from the Chrome Web Store →](https://chromewebstore.google.com/detail/bmdmepddehnpbdffkblbjofgkllmpkgp)**

Lightweight indie internet radio player for Chrome. Plays SomaFM in any browser tab. Manifest V3, vanilla JS, no telemetry.

Sibling to [rangerhq-radio](https://git.davidtkeane.com/ranger/rangerhq-radio) (the WordPress version).

## Tier 1 — MVP (current)

- ✅ Manifest V3 + Offscreen API audio
- ✅ Loads all SomaFM channels from `channels.json`
- ✅ Pick a station, click Play, audio runs in background
- ✅ Volume + state persisted across popup open/close
- ✅ Catalogue cached 6h in `chrome.storage.local`
- ✅ Source-adapter pattern in place for future networks

## Install (developer mode)

1. Open `chrome://extensions`
2. Toggle **Developer mode** on (top right)
3. Click **Load unpacked** → pick this folder (`rangerhq-tuner/`)
4. Pin the extension to your toolbar (puzzle icon → pin)
5. Click the toolbar icon → pick a SomaFM station → ▶ Play
