     No rounded-corner card language appears anywhere in the brand guide,
     wireframes, or photography — Oros products are physical vessels (shells,
     ceramic, wood) photographed in the real world, not app-style rounded
     cards. Kept minimal/sharp with a small radius reserved for tap targets
     (buttons, inputs, swatches) only. */
