/* Device mockup — content-aware iPhone 15 Pro simulation.

   The raw screenshots are plain web-viewport captures (390x844 @2x) with
   no iOS chrome baked in. We reconstruct the iPhone shell in CSS so the
   app content sits in the same visual region it occupies on a real
   device:

     ┌──────────────────────── outer bezel (1)
     │ ┌────────────────────── inner screen (2)
     │ │  09:41       ●●●●    ← status bar (3)
     │ │  ╭─────────╮
     │ │  │ Island  │         ← Dynamic Island (4)
     │ │  ╰─────────╯
     │ │ ┌────────────────┐
     │ │ │                │
     │ │ │  app content   │   ← the captured screenshot (5)
     │ │ │                │
     │ │ └────────────────┘
     │ │        ─────          ← home indicator (6)
     │ └──────────────────────
     └────────────────────────

   34pt bottom inset, ~55pt screen corner radius, 126x37pt Dynamic Island
   centred 11pt from the top of the screen.

   CSS custom properties scale everything off a single `--device-w` so
   hero (260px) and gallery (260px) can share the mock and we can swap
   in larger/smaller widths without retuning each dependent dimension. */
