Owner

Users with both Merlin and Linnet running can use trained Merlin gestures to drive Linnet's composition panel without a second camera pipeline.

Implementation: Merlin daemon exposes a local SSE endpoint at http://127.0.0.1:8522/events that streams gesture events as newline-delimited JSON:

{"gesture": "open_palm", "confidence": 0.94, "ts": 1714180522.3}

Linnet subscribes to this stream (if Merlin is running) and maps gesture events to composition actions (e.g., open_palm → confirm send, head_shake → discard draft).

Phase B feature — implement after gesture event stream is stable and Linnet Phase A is shipped.

Both sides of the SSE connection are localhost-only. No network exposure.
