/* ============================================================
   mobile-shell.css
   Phone / small-tablet shell: compact header, WhatsApp-style
   bottom tab bar and the "More" bottom sheet.

   Breakpoint (max-width: 991.98px) matches MainLayout.razor and
   wwwroot/js/mobile-shell.js. Overrides are prefixed with
   `.app-container` so they beat the inline <style> in MainLayout
   (which is emitted later in the document).
