/* ═══════════ Glass HUD overlays: orientation tour, Tasks roster, account ═══
   The bridge's own overlays on the one glass surface (glass.css): a glass
   pane over the modal scrim rgba(10,14,11,.72), pane titles in the accent,
   22px head titles, mono meta, glass fields and the three button looks.
   Bridge-only: every rule is scoped to body.glass-bridge (login.html and
   auth-link.html keep account.css as it was). Linked after glass-shell.css;
   it replaces tutorial.css and account.css on the bridge.
