   Mixu — "Bàn cắt chìa" design system

   Ý tưởng: sản phẩm ở đây là CHÌA KHOÁ. Chìa thật được cắt từ đồng thau
   trên máy thép. Nên toàn bộ giao diện là bề mặt kim loại phay: nền
   gunmetal, tấm thép dập nổi, nhãn khắc chìm, và đồng thau (brass) là
   màu tương tác duy nhất.

   Ba màu trạng thái mang nghĩa vật liệu:
     patina  #45C7A4  key đang sống
     thép nguội #7FA8CC  key phôi, chưa kích hoạt
     gỉ sét  #DE5B48  hết hạn / khoá

   Mọi token khoá trong :root và [data-theme="light"].
