opus 5.5 video guide: Document and Reproduce Tidy's Dark Tech Launch Film with Animated Windows

Guide to reproducing and documenting a published launch film whose code is attributed to Opus 5.5. Lists prerequisites and build scripts, separates author claims from what the code specifies and what your own run shows, gives an agent prompt requiring absolute-time rendering and fixed seeds, explains checking the MP4 with ffprobe, and asks readers to archive prompts and licenses. No reproduction run is reported.
