Each course module now carries a video record, the generator embeds a
module video block, and the checker requires 15 H.264/AAC 720p videos
between 3 and 8 minutes. The recorder prepares module narration, runs
the module actions with the lesson overlay, records/mixes the video,
and writes per-module reports; it also uses OPFS save/reopen paths.

Generate a static beginner course from course data with real Chromium
screenshots for every module, and record a narrated walkthrough of UV,
Texture Paint, Compositor, Geometry Nodes, Spreadsheet and OPFS reopen.
The render lesson video covers M08/M09; the course page is linked from
the tutorial landing.
