Hero video at /videos/tuxedo-hero.mp4 was hardcoded and 404ing, leaving
the page with no background.
* Add brand_settings.hero_video_url (migration 0099) so each brand
can point its hero at any reachable mp4/webm without code changes.
Saves via a separate UPDATE so the existing 32-param
upsert_brand_settings RPC signature stays untouched.
* TuxedoVideoHero now accepts videoUrl + posterUrl. Poster renders
underneath the <video> element via next/image so the hero is
complete even without a video. <video> flips a data-failed attribute
on error/stall so the poster takes over without DOM churn.
Ambient float animations slowed 950ms → 7s/8s.
* Why section: dropped emerald/amber kaleidoscope, unified accent.
Footer is now a provenance strip (Family-Grown · 5,360 ft · Est 1982).
* Story section: removed giant decorative 'SINCE' parallax text and
the duplicate stats counter (already in hero). Replaced with a
1982/2003/Today timeline.
