+Carries voice/screen control messages, chat, attachments, and state sync — not server-relayed. Data-channel failure triggers peer renegotiation or full rebuild (see realtime README). When a failed control channel is replaced (`replaceDataChannel`), the old channel is closed first so its SCTP resources are released.

+- `removePeer` / `closeAllPeers` clear **all four** remote stream maps, including `remotePeerCameraStreams` (previously leaked per departed peer).
+- Video tiles (`voice-workspace-stream-tile`) pause and null `srcObject` in `ngOnDestroy` (`voice-workspace-stream-video.rules.ts`) so Chromium releases decoder/frame buffers immediately.
+- `debug-network-metrics` drops a peer's entry when the peer is fully removed and caps the store at `MAX_TRACKED_DEBUG_NETWORK_PEERS` = 200 (oldest evicted).
+- Electron registers `setDisplayMediaRequestHandler` once per app run (guarded in `create-window.ts`), not on every window recreation.
