/* aperture.css — the signature of this product surface.
   ----------------------------------------------------------------------------
   Two devices carry the whole visual argument, and everything else stays quiet:

   1. THE APERTURE. A 9:16 window cut out of a 16:9 leader, with the discarded
      margins hatched the way leader tape is hatched. This is literally what the
      pipeline does: find the moment, keep the middle, throw the sides away. The
      aperture is the card frame, the thumbnail, and the empty state at once, so
      the page never needs a decorative image.

   2. THE RULER. Every number that means time or position sits in mono on a
      measured track, because a digit that shifts under you is a digit you
      misread. The ruler is the only place the page is allowed to be loud about
      a number.

   Both are sized from tokens so density, radius and theme keep working.
