Add MEMBERSHIP, the club's own 1980s VHS advert

cut.py --cut ad: a plummy announcer (one gpt-audio read per line, ad.sh)
sells St. Mordred's over the creepiest takes with yellow 80s supers, a
PLAY/STOP VCR read-out, two testimonials from the real lines and the small
print read at speed, until the game's umpire says "Quiet." and the jingle
dies. A VHS grade (chroma smear, scanlines, tape wobble) is the cut's own.
gen.py learns a voice command; one new silent Doris take.

+The club recruits you: a 1989 VHS advert. Announcer reads (`ad.sh`, openai/gpt-audio, one read per
+line so each sits on its shot; spell the club "Saint Mor-dreds" or it is swallowed), yellow Fraunces
+supers, PLAY/STOP VCR read-out, two "testimonials" from the real takes, small print read at speed,
+then the game's umpire: "Quiet." — and the jingle dies. VHS grade: hot colour, chroma smear,
+scanlines, light tape wobble (more than d=0.012 reads as a doubled voice). doris_silent is the one
+new take: an advert cannot have a member's lips moving under the announcer.
