/* site-image-viewer.css — shared modal image viewer
   ------------------------------------------------
   Presentation for the <dialog> injected by js/site-image-viewer.js.
   The browser supplies the modal behaviour (focus trap, top layer,
   Escape); this sheet only paints the darkened full-viewport surface,
   the contained image, its caption and the close control.

   Consumed directly via <link> on article and project pages — the
   typography import keeps its token references valid even when this is
   the first shared sheet in the cascade. */

   own padding acts as the safe-area-aware gutter, and clicks on that
