Two short macro films generated on the local ComfyUI instance (Wan 2.2
14B t2v + lightx2v 4-step LoRAs, 9 clips at 832x480) and stitched with
crossfades and burned-in phase labels: roast-physics.mp4 (charge, drying,
Maillard, first crack, drop) and brew-physics.mp4 (grind, bloom,
immersion, espresso). A "Films — the physics in motion" card on the
Academy menu plays them with posters; opening a lesson hides and pauses
them. The service worker now bypasses /academy-video/ and /academy-audio/
(Range/206 responses the Cache API rejects) and only caches full 200s.
