This is a comprehensive GSAP reference tailored specifically for HyperFrames compositions. It covers the core tween methods (to, from, fromTo), timeline sequencing with position parameters and labels, and the critical HyperFrames contract: register paused timelines on window.__timelines with matching composition IDs so the runtime can seek them. The guide is opinionated about performance (prefer transforms and opacity, use quickTo for frequent updates) and includes practical guardrails like never using infinite repeats since HyperFrames renders finite durations. It even handles responsive animations and reduced motion via matchMedia. If you're building animations in HyperFrames, this gives you everything from basic tweens to complex sequenced timelines without hunting through general GSAP docs.
