The render harness: every screenplay's beats pinned as golden frames

deploy/verify-scenes.sh replays each screenplay to its authored beats
under a paused Playwright clock — pulses, tweens, and fx advance only
on the harness's schedule, so the same beat renders the same bytes
every run — screenshots the reel, and diffs pixels against the goldens
in deploy/scene-goldens (30 frames: warp transits, impacts, curses
landing, in both views). A channel may drift 6 before a pixel counts,
0.2% of pixels before a beat fails; --update blesses intended changes.

Proven both ways before landing: a clean double-run reproduces all 30
goldens exactly, and resurrecting the warp-smear cutaway bug fails the
warp-transit beat at 61% pixel drift.
