/* ── Sets ─────────────────────────────────────────────────────────────────────
   A jeweller's tray: item cards laid three to a row, each showing its gem
   pendants (rendered as inline SVG by src/games/sets/jewel.js). The outer game
   screen is the shared shell; this file is the tray and the slot row — there is
   no footer: the third pick evaluates itself. It borrows the play chrome
   (.q-chrome / .q-stage) from queens.css and adds only Sets's own board. All
   colours come from the --sx-* tokens in tokens.css.                           */
