A minimal Codex skill and starter template building 16:9 card videos from HTML/CSS slides, animated with HyperFrames or GSAP, muxed with a user-supplied audio track via FFmpeg, with no voice-cloning API or publishing pipeline included. Hand the whole repo to Codex, since it references example HTML and output paths. Requires Node 22+, FFmpeg, and HyperFrames.
