/* Styles for everything added on top of the Minimal Mistakes base:
   search, table of contents, changelog, card grids, and the /cerf/ tools.

   All colours go through --se-* custom properties so light and dark are
   declared once. The palette mirrors dark-mode.css (bg #1a1a2e, panel
   #2a2a3e, text #e0e0e0, link #a8c8f0) so the additions do not look bolted on. */
