/* Device frame around screenshots.
   IMPORTANT — do not rotate/skew this element or its img. Even a 1–2deg
   CSS transform forces the browser to resample the bitmap off-axis,
   which visibly softens small UI text regardless of source resolution.
   Visual interest instead comes from elevation (shadow), a soft colour
   glow behind the frame, and a hover lift — all of which leave the
   image itself pixel-aligned and crisp. */
