/* ============================================================
   WA Platform — chat-first design system
   ------------------------------------------------------------
   Familiarity is the product requirement here: users already know
   how WhatsApp works, so the layout deliberately follows that
   mental model (list -> thread -> composer, 3-dot menu for
   everything else). Where we differ from WhatsApp, it is because
   this is a business tool: delivery status is more prominent, and
   the menu is organised by job rather than by settings taxonomy.

   Type is Hind so Hindi/Marathi message bodies render on the same
   baseline as English UI labels.
