   MESSAGES — modern two-pane inbox. Matches the dashboard theme (Montserrat,
   Modern-Clean/Light tokens). Scoped under #messages-redesign so it can't
   leak. Icons: Font Awesome 5 Pro. Responsive: two-pane on desktop, a modern
   message picker + full-width detail on mobile (driven by the controller's
   mailSelectionOption list/dropdown switch at 700px).
