+    title: "OctoPrint camera: go2rtc H264 transcode required for WebRTC"
+    decision: Ender camera (endercamera.duckdns.org) streams MJPEG only; go2rtc serves it
+      transcoded to H264 (ffmpeg:...#video=h264) because WebRTC cannot negotiate MJPEG.
+      Keep this transcode. The printer-stats dashboard webrtc card uses go2rtc's named
+      'octoprint' stream, never a raw URL.
+    rationale: "Fixed the webrtc-camera card's DESCRIBE error (dead
+      rtsp://127.0.0.1:18554/octoprint) and 'codec not matched' error (MJPEG over WebRTC).
+      Operational trap discovered: do NOT POST to go2rtc /api/config - it persists its
+      JSON body into go2rtc.yaml, silently overwriting config. To change streams, edit
+      /homeassistant/go2rtc.yaml and reload the webrtc integration (entry
+      01KWT295KFJ9V0N6ZXG88JM3GA); the embedded go2rtc reads that file on reload."
