 API, encodes them through VideoToolbox, and writes the resulting H.264 samples
 to the same WebRTC video track.
 
+Loopback Android clients may pass `"transport": "rgba"` in the offer payload.
+That keeps the same WebRTC endpoint and control channels, but sends raw RGBA
+frames over the `simdeck-rgba` data channel instead of creating a media track.
+Non-loopback Android clients use encoded H.264.
+
 The browser also opens `simdeck-control` and `simdeck-telemetry` data channels.
 In addition to input messages, clients can request a keyframe or tune the
 stream attached to that peer:
 
-### `GET /api/simulators/{udid}/android/frames`
-
-Android-only WebSocket stream backed by the emulator gRPC `streamScreenshot`
-API. This is retained as a raw-frame diagnostic/fallback path; the browser live
-view uses the WebRTC H.264 endpoint by default. The server sends binary raw RGBA
-frames with a small SimDeck header, already flipped into top-down row order for
-canvas rendering.

 The Rust server runs the tokio runtime on a worker thread while the AppKit main loop spins on the main thread. The native bridge needs the main loop to deliver display callbacks and HID events.
