/* ==========================================================================
   .content-body  —  typography for long-form CMS content on the PUBLIC site.

   This is what renders the rich text the admin editor produces. It lives in
   /public/assets/css next to the template's own stylesheets and is loaded with
   a plain <link> by the pages that need it, so the ported NAMU template's
   cascade is untouched: nothing here applies outside `.content-body`.

   THE RULE THAT MATTERS: every rule in here that changes how CONTENT looks must
   also exist in the editor's stylesheet (src/app/admin/admin.css, the
   `.rte .ProseMirror` block). When the two drift, the editor shows the author
   something the visitor will not see — which is the single most annoying class
   of bug in a CMS.

   Colours come from variables so the site's accent is set in one place. The
   accent follows the site theme colour (--bs-themecolor from color-red.css),
   so links, bullets and rules match the rest of the site.
