Backend:
- GET /api/zone/{id} — zone info enriched with device names and role flags
- POST /api/zone/{id}/add/{slaveId} — add slave (creates zone if standalone)
- POST /api/zone/{id}/remove/{slaveId} — remove slave from zone
- POST /api/zone/{id}/dissolve — dissolve zone to standalone
- POST /api/zone/{id}/leave — slave leaves its zone (backend finds master)
Frontend (Zone.js):
- Standalone: shows "Group with…" button, opens device picker overlay
- Master: member list with per-row Remove, Add speaker, Dissolve buttons
- Slave: shows master name, Leave zone button
- Lazy-loads on device detail open; refreshes after each zone operation

Move soundtouch-web from Bootstrap+vanilla JS to an embedded-asset Go service
using Preact+htm (no build step). Implements Stockholm UI parity: device list,
now playing, transport controls, presets, sources, and TuneIn browser.
- Relocate handlers/websocket/webtypes to pkg/service/soundtouchweb/
- Replace old static/ with CSS-custom-property design system (dark mode)
- Add Preact component tree: DeviceList, NowPlaying, Controls, Presets, Sources, TuneInBrowser
- Wire WebSocket for real-time device status updates
- Slim cmd/soundtouch-web/main.go to a thin CLI wrapper
