/* Time Warp Scan — "neon night lab".
   The camera screen and the picture always sit in a dark #0A0B1A frame; the
   landing page and the sheets follow the theme (light paper / deep ink).
   Titles and numbers in a crisp monospace, text in a geometric sans; cards
   16 px round, buttons 12 px, chips pills; the red bar is the one hot colour.
   Motion: transform/opacity only, springs for things that arrive, quick
   fades for things that leave; reduced motion turns travel into crossfades. */
