/* Sample works: the home band, and /samples/<book_id> (templates/samples/).

   Every colour is a --gk2-* token, so a shop's theme (theme-koala.css) re-points
   this sheet with nothing written here. Every horizontal position is LOGICAL
   (inline-start / inline-end), so the Persian shop mirrors it by its own `dir`;
   the arrows and chevrons are the only things turned by hand, because an SVG
   path has a direction of its own. */
