The visuals entry was wrong in its premise, and the correction matters more
than the task: xps22 came up and showed that `visuals/scenes/` already exists
(14 mp4s, 197 M), that the HUD's scenesDir already points at it, that the gifs
were already compressed on 2026-08-29, and that committing them was
DELIBERATELY rejected in .gitignore with the reason written in. The "16 dangling
url refs" are working as designed — scenes.js:_preferDerived() documents that
the header points at the SSOT source and the HUD substitutes the derived mp4.

So the plan "one home, compress, rewrite refs repo-relative" proposed doing
three things that were already done or already decided against. The remaining
work is a 197 M copy, and the entry now says so. Kicked a fence before reading
why it was there.

Jig decision 1 answered: ONE STABLE JIG, swept every time. Recorded with the
two consequences that follow — ARDOUR_SESSION stays fixed, and "self-contained
per gig" must now come from take metadata, which folds question 2 into it.

Also opened: the Ardour fader feed's verified findings (Ardour has already
learned CCs 13-16; only "midi-feedback"=0 withholds the values; Midi Through is
a loopback so the feedback leg needs its own port), ../tidal-ears not being
cloned here, and pytest being absent from the very interpreter the rig runs.
