/* Mobile drawer menu — shared by every page (see static/js/mobile-menu.js).
   Plain CSS on purpose: static/css/tailwind.css is a pre-built static file,
   so new Tailwind classes would silently not exist in it. Colours are the
   live navbar's tokens: #3D2010 brown, #6B3E1E secondary, #D97706/#B45309
   amber, #F5E6C8 gold, #F7EDDD hover, #DBC2B0 border, #DC2626 sign-out. */
