/* BioStudio AI — shared chrome for the layout-first styles
   (Folio, Ink, Block, Orbit, Bench — see js/platform/novel-styles.js).

   Each style's own sheet (css/shell-<id>.css) sets:
     • its --ct-* palette for White and Black, so the shell's legacy tokens
       and the app content of White windows (which read --mono-*) follow it;
     • the --nv-* tokens below (type, radii, borders, shadows, controls);
     • its bar / hub / status line and launcher layout.
   This file turns the tokens into windows, menus, flyouts, dialogs,
   notifications, desktop icons and scrollbars. Scoped to `.novel-shell`,
   which the shell adds to #os and <body> only while one of them is active. */
