 /**
  * Composable pour gérer le WebRenderer navigateur.
  *
- * Se connecte automatiquement au WebSocket /api/webrenderer/ws au montage
- * et se déconnecte proprement au démontage ou à la fermeture de la page.
+ * S'enregistre via POST /api/webrenderer/register au montage
+ * et diffuse l'audio via un élément <audio> pointant sur
+ * /api/webrenderer/{id}/stream (flux FLAC encodé côté serveur).
  *
- * Le navigateur est ainsi vu comme un renderer UPnP par le ControlPoint.
- * L'audio est géré via deux éléments <audio> en ping-pong connectés à un
- * AudioContext (MediaElementSourceNode) pour le contrôle du volume/mute.
+ * Le navigateur est vu comme un renderer UPnP par le ControlPoint.
+ * Le gapless est géré côté serveur : le navigateur lit un flux continu.
  *
- * ## Flux gapless
- * 1. SetAVTransportURI(N)     → slotA.src = N, slotA.load()
- * 2. Play                     → slotA.play()
- * 3. SetNextAVTransportURI(N+1) → slotB.src = N+1, slotB.load() (préchargement)
- * 4. slotA "ended"            → currentSlot = B, slotB.play() immédiat
- *                               → TrackEnded envoyé au backend
- * 5. Cycle recommence depuis 3 (slotA redevient le "next")
+ * Cycle de vie du flux audio :
+ * - PLAYING/TRANSITIONING → src = stream_url + play()  (nouvelle connexion HTTP)
+ * - PAUSED/STOPPED        → pause() + src = ""          (déconnexion HTTP)

+//! - **Play** : le navigateur appelle `GET /stream`. `connect()` crée un nouveau
+//!   canal PCM + pipe duplex + encodeur FLAC, installe le sender dans le sink,
+//!   et notifie le sink via `client_notify`. Le flux reste ouvert : les morceaux
+//!   s'enchaînent en gapless.
+//! - **Stop** : le navigateur ferme la connexion. Le pipe se rompt, l'encodeur
+//!   s'arrête. Le sink voit `pcm_tx.send()` échouer, passe le sender à `None`,
+//!   et **bloque** sur `client_notify` jusqu'au prochain Play.
+//!   Cela bloque la source et préserve la backpressure.
+//! - **Play suivant** : `connect()` → nouveau pipe → `client_notify.notify_one()`
+//!   → le sink se débloque et reprend la consommation des segments.

+//! Combine la logique de backpressure/reconnexion de `DirectFlacSink`
+//! avec l'encodage OGG-FLAC de `StreamingOggFlacSink`.
+//!
+//! # Cycle de vie
+//!
+//! - **Play** : le navigateur appelle `GET /stream`. `connect()` crée un nouveau
+//!   canal PCM + pipe duplex + encodeur FLAC + wrapper OGG, installe le sender
+//!   dans le sink, et notifie le sink via `client_notify`. Le flux reste ouvert :
+//!   les morceaux s'enchaînent en gapless.
+//! - **Stop** : le navigateur ferme la connexion. Le pipe se rompt, l'encodeur
+//!   s'arrête. Le sink voit `pcm_tx.send()` échouer, passe le sender à `None`,
+//!   et **bloque** sur `client_notify` jusqu'au prochain Play.
+//! - **Play suivant** : `connect()` → nouveau pipe → `client_notify.notify_one()`
+//!   → le sink se débloque et reprend la consommation des segments.
