/* ═══════════════════════════════════════════════════════════════════════════════
   T-Mayee WhatsApp Dashboard — design system

   Structure:
     1. Tokens (light + dark)
     2. Reset & base
     3. Primitives (buttons, fields, chips, cards, tables)
     4. App shell (rail + views)
     5. Inbox (list, chat, message bubbles, composer, details)
     6. Marketing / Automation / Contacts / Analytics / Settings
     7. Overlays (modal, lightbox, toast, menu)
     8. Responsive

   Themes: `:root` holds the light palette. Dark is applied both by
   `[data-theme="dark"]` (explicit choice) and by prefers-color-scheme when no
   explicit choice was made, so "System" genuinely follows the OS.
