Each one is a real, evidenced pain with no good answer elsewhere, and each ends at the component that solves it.

An AOS alternative for Astro
AOS keeps animated elements invisible until its script runs, shows elements without animating them after a ClientRouter navigation, and has had no release since October 2018. Reveal does the same job without those problems.
GSAP ScrollTrigger with Astro View Transitions
Why ScrollTrigger stops working after a ClientRouter navigation, and the adapter that sets it up on every page and cleans up before the next one.
Lenis smooth scroll with Astro's ClientRouter
A navigation made while Lenis is still easing scrolls the next page to the old page's target. lenisPage stops the animation and resyncs Lenis after every ClientRouter swap.

Recipes

Short compositions, copy-paste.

Scroll-driven hero

SplitText headline over Aurora, Reveal for the copy.

Staggered card grid

One Reveal with stagger, cards as children.

Animated stat row

Reveal stagger plus RotatingText for the claim.

The agent skill

The craft behind the library (the cost ladder, curves, durations, the porting method and the Astro runtime rules), packaged as a skill for Claude Code, Cursor and Codex. It is what generated this catalogue. Set it up alongside the MCP server.
