Render real video from plain HTML, CSS, and GSAP

A video is just an HTML page with a clock. HyperFrames (HeyGen's open-source framework) seeks a paused GSAP timeline to exact timestamps and captures each one as a frame — no timeline-scrubbing editor, just markup, CSS, and GSAP driving it. This guide teaches the mental model (why everything must be seekable/deterministic), six copy-paste recipes, and a five-pitfalls section on the mistakes that cause blank renders or frozen frames. Independent guide, not affiliated with HeyGen.
