/* ============================================================
   css/cms-content-theme.css
   Universal reading theme for CMS-rendered content (.cms-content).
   Applied once, automatically, to every blog post AND every CMS
   page rendered through core/page-template.php — no per-post
   styling needed.

   Deliberately reuses the site's existing --font-main / --font-body
   / --sky-deep / --radius / --shadow tokens from css/style.css
   instead of introducing a new webfont — a prior CLS fix already
   tuned font loading sitewide, and pulling in another font family
   here would risk reintroducing that same layout-shift problem.
