Two gaps in what 7f89534 shipped, both caught by the creator's report that sound still
leads the lips:
- The mic delay had presets only (off / 150 / 200), so the value a slower camera needs —
roughly 175 ms of residual on top of the 175 ms already applied — could not be set at
all. Now a 0..500 ms slider with off / 175 / 350 presets.
- Nothing recorded which number was in force. The setting lives in the layout DB, so a
preset click left no trace in the log; "Audio live: started" now names it.
Confirmed meanwhile from the profile: Audio.MicSyncOffsetMs is 175, so the delay is being
applied — the 150 ms of digital silence at the head of the 12:22 track is the delay line
priming, which is what an applied delay looks like. The residual offset is the camera's
pipeline being slower than 175 ms, not a missing delay.
