  "what": "Framework-agnostic animation engine whose differentiator is the timeline model: sequence, offset, nest, reverse and scrub complex choreography with precise control. ScrollTrigger handles scroll-driven and pinned animation; SplitText does per-character reveals.",
  "why": "<b>This is the scrolled-feature-article tool.</b> Pinned photo sequences, a headline that assembles as you scroll, a timeline piece that scrubs — that is ScrollTrigger, and nothing else comes close. Webflow acquired GreenSock and made every formerly-paid plugin free in 2025. Core + ScrollTrigger + SplitText is ~49 kB gz.",
  "warn": "Free but <b>not OSI open source</b> — a custom Webflow-owned licence that bars using GSAP inside competing no-code animation builders. Building scroll-driven features with it is squarely permitted. Release cadence has slowed to 2–3/year under Webflow.",
