Current Work (newest first)

[2026-02-20T11:35:13Z] handoff: switched README.md demo embed to GitHub-mobile-safe GIF-first pattern (linked image + explicit WebM/MP4 links).
[2026-02-20T11:34:27Z] handoff: generated assets/minecard.gif (960x540 @ 12fps) and mirrored to docs/public/assets/minecard.gif; updated README.md + docs/index.md video sections to embed GIF fallback when video unsupported.
[2026-02-20T11:34:27Z] test: verified media files exist and fallback refs present via rg; GIF dimensions/fps validated with ffprobe.
[2026-02-20T11:33:36Z] intent: create GIF fallback from assets/minecard.webm; update README.md + docs/index.md video sections to include fallback content for unsupported video.
[2026-02-20T11:29:35Z] handoff: created assets/minecard-image-1.png from assets/minecard.webm at 00:00:10; verified 1920x1080.
[2026-02-20T11:29:35Z] test: confirmed output file exists and dimensions via ffprobe.
[2026-02-20T11:29:09Z] progress: updated subagent index/own record for this session.
[2026-02-20T11:29:09Z] intent: extract a new still image from assets/minecard.webm; keep change minimal.

User wants a still frame image generated from the video source.
User now wants GIF fallback available where WebM playback may fail (README/docs).
