   Bottom-sheet réutilisable
   - Sur desktop (>= 760px) : modal classique centré
   - Sur mobile (< 760px)  : feuille collée en bas, swipe-down pour fermer
   À importer après _tokens.css :
       @import url('/static/css/_bottomsheet.css');

   Markup attendu :
       <div class="bs-overlay" id="..." role="dialog" aria-modal="true">

           <div class="bs-handle"></div>
