   Modal — clases reusables. Antes cada modal tenía 6+ inline styles
   copiados que diferían en opacidad de backdrop, padding, etc. Ahora
   la escala visual queda consistente y el ESC/backdrop click se
   maneja centralizado en app.html (_closeTopModal).

   Uso típico:
     <div class="modal-overlay" id="X-modal" data-modal>
       <div class="modal-card">
         <div class="modal-header">
           <h3>Título</h3>
           <button class="modal-close" data-modal-close>×</button>
         </div>
         <div class="modal-body">...</div>
