+// The audio graph (AudioContext + MediaElementSource + AnalyserNode + DelayNode)

+// Whether the visualiser actually animates depends on the audio source being
+// CORS-clean:
+//   - In Electron, the main process injects `Access-Control-Allow-Origin: *`
+//     on media responses, so direct Icecast streams work.
+//   - In a plain browser, the player routes through the same-origin
+//     `/api/stations/:id/proxy` endpoint whenever room sync is active, which
+//     also makes the analyser readable. Solo-mode playback in a plain browser
+//     uses the direct stream and the analyser will read silence-of-data —
+//     that's a fundamental browser CORS constraint, not a bug here.
