   SMALL-SCREEN ADJUSTMENTS
   On narrow / portrait viewports:
   - Show the FULL video frame (object-fit: contain) instead of
     cropping the sides off — fixes the "video doesn't fit phone" bug
   - Shrink the reel so phone scrolling isn't endless
   - Captions move just above the bottom letterbox, larger touch-safe text
   - Center the watermark mask on the video's actual bottom-right
     (which when contained on a portrait phone sits at the mid-band edge,
     not the stage corner)
