chore: v0.5.3 — bump version + CHANGELOG entry

Final headline-feature release. Per David: 'this app is kinda done'
once Quick Stations picker + history export ship. After this version,
polish remains but no headline features are missing.

Bundled with v0.5.0's eventual Web Store upload — when v0.5.0
clears re-review, we'll build a v0.5.3 ZIP directly from main and
upload that as the next user-visible update. Users at v0.4.0 jump
straight to v0.5.3, getting all the polish in one notification.

+## [0.5.3] — 2026-06-10 — User-customizable Quick Stations + history export ("app is done")
+
+Per David: *"this app is kinda done"* — meaning the product surface is feature-complete. After this version, polish remains but no headline features are missing.
+
+### Added — User-customizable Quick Stations
+
+Pure-data architecture: the NewTab Quick Stations chip row is now driven by `tuner.quickStations` in `chrome.storage.local` rather than a hardcoded `QUICK_IDS` array. **Default 8 (tidy 2-row layout, matches v0.4.0 look).** User can pick any subset of all 46 SomaFM channels via a new Options page card.
+
+**Where:** new "Quick Stations" card on the Options page (sits between Appearance and Playback). Layout: helper text + selected-count badge + scrollable checkbox list + Reset-to-defaults button.
+
+**Each list row** shows: checkbox + station name + genre pill (accent green, uppercase) + the SomaFM channel description (the same string available as a chip-hover tooltip on the NewTab — now properly visible at the time of picking).
+
+**Live sync:** ticking a checkbox writes to `chrome.storage.local`. The NewTab `chrome.storage.onChanged` listener picks up the change and re-renders the Quick Stations chip row instantly without a reload. Cross-surface consistency is the same pattern as theme + station selection.
+
+**Robust fresh-install fallback:** if Options is opened BEFORE the NewTab has ever populated the station catalogue cache, `initQuickStationsUI` fetches SomaFM channels directly via `listAllStations()` then caches the result back to `tuner.stationsCache`. Future Options opens are then instant.
+
+**Empty-pick case:** if the user unticks everything, the Quick Stations row on the NewTab shows *"No Quick Stations picked — set some in ⚙ Settings."* instead of a silently empty section.
+
+### Added — History export (JSON + CSV)
+
+Two new buttons in the Local Data card: **Export history (JSON)** and **Export history (CSV)**.
+
+- **JSON**: full pretty-printed array of `tuner.history` entries. Best for programmatic re-import or backup.
+- **CSV**: RFC 4180 quoted (every cell quoted, doubled quotes for embedded quotes). Header: `artist,title,station,station_id,when_iso`. Opens cleanly in Excel / Numbers / Google Sheets.
+
+Filename: `rangerhq-tuner-history-YYYY-MM-DD.{ext}`.
+
+Empty-history case shows an error toast ("No history to export yet — play some music first"). Success case shows a green toast with the export count and format.
+
+No new permissions — uses standard `Blob` + `URL.createObjectURL` + a programmatic `<a>` click. The entire export runs client-side in the Options page; nothing is sent off-device.
+
+### New / changed files
+
+- `src/lib/quick-stations.js` (NEW, ~55 lines) — `DEFAULT_QUICK_IDS` constant + `getQuickStations / setQuickStations / resetQuickStations` helpers. Same defensive `storage()` accessor pattern as `lib/history.js` and `lib/theme.js`.
+- `src/newtab/newtab.js` — removed hardcoded `QUICK_IDS` array, replaced with module-level `quickIds = []` populated during `init()` from `getQuickStations()` and re-loaded when `chrome.storage.onChanged` fires on `tuner.quickStations`. `renderQuick()` shows the empty-pick fallback message.
+- `src/options/options.html` — new "Quick Stations" card + two export buttons in the Local Data card.
+- `src/options/options.css` — ~90 lines for the picker (scrollable list, row layout, accent-coloured count badge, hover background, brand scrollbar).
+- `src/options/options.js` — `initQuickStationsUI` builds the checkbox list, `onQuickStationToggle` persists picks, `exportHistoryAs` generates the download Blob. Plus the storage.onChanged listener was made async to support cross-surface picker sync.
+
+Total: 5 files, +372 / -25 lines (1 new file).
+
+### Not changed
+
+- No new permissions
+- No new host_permissions
+- No new external libraries / SDKs
+- No data migration required
+- Existing user state (current station / volume / history / favourites / theme) survives intact
+- Defaults match v0.4.0's curated Quick Stations exactly — users who never open Options get the same look they had before
+
+### Workflow note
+
+This release was bundled into v0.5.0's eventual Web Store upload — when v0.5.0 clears re-review, we build a v0.5.3 ZIP directly from main and upload that instead. Users at v0.4.0 jump straight to v0.5.3 (skipping v0.5.0, v0.5.1, v0.5.2) and get all the polish in a single update notification.

 ## [0.5.2] — 2026-06-10 — Quick Stations fix: replace retired BAGeL with PopTron
 
 Hotfix for v0.5.1's Quick Stations row. David flagged: *"the stations still look a bit off"* — turned out only 13 chips were rendering instead of the intended 14. Investigation showed **BAGeL Radio has been retired from SomaFM's current `channels.json` catalogue** — the render loop's "drop missing slugs silently" behaviour (working as designed) made the chip just disappear.
