   Add Sources Overlay — shared component
   Used by both /studio and the AI Assistant on /. Markup is injected by
   /js/add-sources-overlay.js; this file only carries the styles.

   Depends on the page-level CSS variables already in place
   (styles.gopdf-rebrand.css supplies them on every page that uses Studio's
   visual language): --bg2, --surface, --text, --text2/3/4, --border,
   --border-strong, --gold, --gold-dim, --teal, --teal-dim, --btn-bg,
   --btn-text. No new tokens.
