Individual skill
gsap-vanilla
Build or review animation on plain HTML/CSS/JavaScript sites: GSAP page intros/outros, component show/hide, scroll effects, cross-document View Transitions, bfcache, and fetch/swap navigation with Swup, Barba, or Taxi. Use for first-paint flashes or interrupted navigation, even when GSAP is unnamed. Also covers hidden-content recovery and first-load performance. Not for component frameworks or isolated GSAP API questions.

# GSAP Vanilla
**mount → initial state → intro → settled → outro → end state → unmount**
On full document loads, the browser owns mount and unmount; animation owns the five phases between them. On same-document swaps, the router owns node replacement and persistent resources need explicit cleanup.
Keep the requested look and existing project conventions. Add GSAP/plugins only as needed; do not replace the chosen animation library unless asked.
