/* =====================================================================
   HANDPICKED COLLECTIONS
   A heading with a pair of arrows opposite, over a sideways row of tall photo
   cards. Each card carries a "TOP n" pill above its name and sits on a second
   card peeking out behind it — the stack is what says "collection" rather than
   "one more photograph".

   No panel and no white: the page's own gradient is the ground, so the row
   reads as part of the page.

   Class prefix `kcoll` / `collcard`, checked against every stylesheet before
   use — `.pcard`, `.krail` and `.kdeal` were all already taken.
