/* Scoped to .md-typeset so it applies to images in page content only — the header
   logo and footer social icons must stay borderless. */

/* Screenshots and diagrams are mostly white or mostly dark, so they bleed into the
   page background in whichever theme matches them. The border keeps the image edge
   visible in both. */
