 - New test `MediaSourceAcquisitionTests` (add → one decoder starts + frames reach the layer + loop flip
  reaches the decoder + remove → stops). App build is 0 warnings.
- Volume is deliberately unwired: media audio rides the desktop loopback, so a slider would do nothing.
+- **Media is picture-only:** `MediaVideoSource` decodes with `-an`, so a video file's own soundtrack
+  is silent on stream — the loopback does not carry it because nothing plays it. Two routes recorded
+  in `task-21` item 10 (alert-style mixer feed vs TRAX-style local play); no volume slider until one exists.
