/* ── Dark mode (opt-in — commented out) ───────────────────────────────────
   Dark mode for a rendered block is the SITE's responsibility, not the plugin's.
   Every color above is a CSS variable, so redefine the palette below under
   whatever trigger your site uses. Uncomment and point the selector at your
   site's theme system. Bar/line use the accent color you configured; donut
   slice colors come from a fixed palette.
   NOTE: `.dark` is also the ContentBuilder editor's own UI theme, so on a page
   that runs the editor, prefer a different class here.
