Tighten the trailer to 1:30 and fix its two audio faults

Browse Source 
Cut 3 of LIFETIME MEMBERS: the intro music no longer runs into Reg's first
line, Ambrose finishes "...still waiting for a result" (line ends are now
measured off each take instead of the QA transcript), every shot is
tighter, and the black title cards are set larger. Cut 2 stays on disk
beside it as the reference.

- QA listening (`qa.py`, Gemini): trust it on spoken lines and on mix complaints, NOT on its
timestamps for music (they drift up to 1.5x) and not on transcripts of non-speech audio
(it invents words from footsteps).
## Cut 2 → cut 3 (Oliver, 2026-10-05) — 1:45 → 1:30, cut 2 kept as the reference
- The intro music ran 3 s into Reg's "Fertiliser": it now fades out under "How did it start?".
- Ambrose lost the end of "...result": cut 2 trusted the QA transcript's 6.6 s; the take's speech
envelope says 7.2. Every line end in the EDL is now measured off the take, not the transcript.
- Tighter everywhere (B-roll 2.2 s, cold open 14 s, shorter cards and logo); the black cards'
text is bigger (88/96 px Baskerville, balanced wrapping).
