/* =================================================================
   MARS — bottom-sheet.css
   Nouveau fichier. À inclure après style.css.
   =================================================================
   Pattern "bottom sheet" : remplace les modals centrés pour les
   formulaires mobiles. Fournit :
   - scrim cliquable
   - grip en haut (drag-to-dismiss)
   - actions sticky en bas
   - respect safe-area-inset-bottom
