/* ── Подарочные сертификаты ─────────────────────────────────────────────
   Each certificate is drawn as the gift card itself: a coloured face (colour by
   face value, ribbon + bow), a perforated tear line, and the working stub below
   — number, PIN, status, validity, buyer, actions. Faces use fixed colours on
   purpose: a card is an object, it looks the same in every mood of the panel. */
