Hello panglesd, glad you like it, enjoy.
The video was made by me. With real recordings, capturing the screen running Quarter in Windows Terminal at 4K, so the zoom looks nice when downscaled to 1080p. Then edited with HyperFrames where videos are written as HTML, then rendered to MP4. Claude Code wrote the brief following my prompt.
