<title>Scene 3 — Assembly Focus Reveal (hyperframes)</title>
<!--
HyperFrames composition.tsx.
Choreography (5 phases, 5 seconds total):
0.00 – 0.67s "Just use" assembles in a discrete sequence (with hold)
0.73 – 1.23s Pink logo pops in with back.out elastic
1.50 – 2.20s "Just use" slides left + fades; container recenters around brand
2.67 – 3.57s Camera zooms 5.5× into the logo (scale + counter-translate)
3.67 – 5.00s Logo breathes (sine onUpdate, multiplicative on pop scale)
Key differences :
- Single paused GSAP timeline registered to window.__timelines["main"]
- brandTextWidth measured via getBoundingClientRect after document.fonts.ready
- HERO_FINAL_OFFSET_X derived from real measurement, not estimate
- Breathing uses the onUpdate (multiplicative) form so it multiplies
onto the pop scale, not a fromTo + yoyo which would overwrite the pop value
- Three nested transform layers: zoom-scale → zoom-translate → recenter-shift
- Logo is loaded from a static PNG asset
