hyperframe

Thin router to HeyGen HyperFrames — the HTML-native motion-graphics engine (write HTML, render deterministic MP4 locally via headless Chrome + FFmpeg). Use when the user says "hyperframe", "hyperframes", "animated overlay", "motion graphics", "html to video", "animated caption", "animated hook text", "kinetic captions", "kinetic titles", "end card", "lower third", or wants to author/render an HTML composition to MP4 or browse the HyperFrames block catalog. NOT for generative video (that is /vidgen) and NOT for StayFrame static text overlays (that stays on /jstack-sf-caption).
