/* ==========================================================================
   The Reel — Ken Burns video maker.

   Reuses the shared dk-* instrument components from darkroom.css; this sheet
   adds the reel-specific layout (preview + photo strip), the 3×3 focus
   picker, the render progress bar, and re-declares the photo-tray primitives
   (shared visually with the collage tray, but that sheet isn't loaded here).
   Flat design only — solid colours, no gradients. Scoped under .pt-scope so
   it inherits the instrument tokens.
