/* AI Signal prototype — the reel composition and the immersive Watch player.
   Part 1 (.reel…) is the composition itself: everything a HyperFrames template would render into the shared MP4,
   including burned-in captions. It is sized in container units so it looks the same at any size.
   Part 2 (.watch…) is the player chrome around it, which is never part of the video. */
