/* ── A phone frame ──
   A real app screenshot inside a phone drawn in CSS (STYLING.md > A phone
   frame): an `8px` bezel in `--theme-palette-color-4`, the site's dark
   ground, with concentric corners, `32px` outside and `24px` on the display,
   and the Card shadow tier. The frame takes its width from its container.

   The display is a status bar over the screen. The captures have the phone's
   own status bar cropped off, so the frame draws one: dark, as the app paints
   it (the site's dark ground), with the time on the left, signal, Wi-Fi and
   battery on the right in white, and the camera hole centred between them.
   Its height is the Android status bar's share of a 720px-wide capture
   (`48px`), and everything in it is sized in container units, so it keeps
   its proportions at every phone width.

   The screen keeps the screenshots' own 720 × 1444, so nothing is cropped,
   and holds that shape before the lazy image arrives. The images sit
   absolutely in it, so one screen can stack several.

   What else makes it read as a phone rather than a dark card, all in the
   bezel's colour: a faint light rim on the bezel's edge, and the side
   buttons (power and volume on the right, as on an Android phone, since the
   screens are the Android app's). */
