/* SANEXTA Collab: additions to the binding SANEXTA stylesheet (static/css/sanexta.css).

   Rules of this file (CLAUDE.md, "Frontend und Design"):
   - sanexta.css is never changed; this file is loaded after it.
   - No colour values: only var(--...) from sanexta.css. A token of its own would go into the
     same three theme blocks as there (:root, [data-theme="dark"], prefers-color-scheme).
   - Logical properties only (margin-inline-start, inset-inline-end, ...), so Arabic (RTL)
     mirrors without special rules.
   - Every section names the markup it belongs to. */
