/* Screenshots — uniform framing across every page. The app screenshots are always captured
   in the app's dark theme (its true default). Elevation, not enclosure: no border, no matte
   band — the screenshot's own dark edge against the page plus a generous soft shadow is
   enough definition on its own, so it reads as a card floating just above the page rather
   than a picture boxed into a frame. One class, no per-image markup. Adjust the look
   everywhere at once via the --shot-shadow token above. */
