zooqueen 62bbc7766c skills: give each skill the directory its name declares
Every SKILL.md already declared the new name — name: frames, frames-cli,
frames-core, and so on — but the directories were never moved, so the tree
carried frames-* in content and hyperframes-* on disk. Everything that
resolves a skill by path missed: the core-skill list, the plugin marketplace
pin, and the docs the CLI reads at runtime. Eight tests failed on main because
the files they open do not exist.

The directories now match what the files say they are, and the guide the
claude-design contract reads takes the name that contract already used.

<title>Scene 3 — Assembly Focus Reveal (frames)</title>
<!--
Frames 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
