/* MedVault Biblioteca tab (C1 medlib2 bridge + C2 composer, ADR-007).
   Loaded once via <link> in index.html. Scoped under .biblioteca-tab so it
   cannot leak to other tabs.

   Uses the project-wide --surface / --bg / --border / --text / --accent
   token family (style.css :root + :root[data-theme="dark"]), so dark mode
   just works. Reuses .search-box / .data-table / .btn / .btn-primary from
   style.css where possible. */
