feat(opal26): re-render complete — seam edits applied, close A/B ready

Full pipeline run on the edited segments. All green:

  split      14 tracks x streaming + club
  verify     every duration exact, 48000/24
  continuous 14 segments, 72.6 min, 3 gaps -> 4358.70s both variants

The three gaps are the trims, and seeing them enumerated is the point:
  [ 530.35 ..  531.35]    1.00s   the silence PLN wanted cut to 1s
  [ 892.96 ..  893.00]    0.04s   WAP's truncation burst
  [4156.30 .. 4566.47]  410.17s   Desire, plus his CRIME/REVOLUTION trims

Verified the WAP fix by measurement rather than by assuming the trim landed:
peak in the track's last 100ms is now -55.0 dBFS, down from -15.1, and it decays
to -70 instead of being chopped mid-transient. What remains near the end is
ordinary music ringing out into the 30ms guard fade, which is the intended
result — the truncated sound is gone, not merely quieter.

Release-check set rebuilt: 17 clips (open + 13 seams + 3 closes). Smoke passes
against the production server.
