- 00_Demo: 38 demo videos (mp4, landscape pixels + rotation -90, faststart),
  same files and order as the USB 00_Demo_Video folder, so they play back-to-back
- 10_Source/4K, 10_Source/FHD: original sources moved (BTS SWIM x2 removed)
- README: folder layout, playback order, file rules for new content
- .gitignore: converted/ and _local/ work files stay local
