 - Clip duration is clamped (currently `<= 60s`) to avoid oversized base64 payloads.

+## Screen recordings (mac node)
+
+Mac node mode exposes `screen.record` (mp4). Example:
+
+```bash
+clawdis nodes screen record --node <idOrNameOrIp> --duration 10s --fps 10
+```
+
+## Mac node mode
+
+- The macOS menubar app connects to the Gateway bridge as a node (so `clawdis nodes …` works against this Mac).
+- In remote mode, the app opens an SSH tunnel for the bridge port and connects to `localhost`.
