   10-A11Y-WIDGET — PAINEL DE ACESSIBILIDADE
   Botão vive na .nav-right (não é FAB flutuante).
   Sidebar lateral deslizante — sem backdrop, sem blur.
   Integra-se com os tokens de 01-root.css e o sistema
   de data-font / data-theme / lang já existentes.

   Ordem de import em styles.css:
   @import '10-a11y-widget.css';   ← após 09-accessibility
