/* ============================================
   ★★★ DEVICE MOCKUPS — SIMPLIFIED FOR HTML2CANVAS ★★★

   Key principles:
   - No complex inset shadows that html2canvas breaks
   - No nested overflow:hidden chains
   - Background: black only on screen-area (single layer)
   - <img> directly inside screen-area with object-fit
   - All transforms on the img itself (not wrappers)
