/* ══ Rolling counter ═════════════════════════════════════
   Bencho's slab, fitted to Borhe. Tokens are mapped on the
   component root so they do not leak into the page.
   --card / --fill-slab  surface the keys sit on
   --fill-on / --ink     text and icon ink
   --font-ui             the UI face already in use
   --pane-edge           the field's hairline
   --signal              focus, the theme's primary / ring

   The repeat row's other control is a 54px pill. The counter
   fills that pill and centers a 32px key in it. The key corner
   is 16px, a circle. Admin fields keep the 10px field radius;
   their keys step down to 6px. Neither size uses 8 or 12. */
