/* ================================================================
   Shared Chat Widget — Emma (AI Insurance Assistant)
   Standalone CSS — not processed by Tailwind.
   Phase 6.2 consolidation: one source of truth for 5 sites. Per-site
   theming via CSS custom properties set on :root or .chat-widget in
   each site's main.css / base.njk. site-whole uses its own emma-*
   fork in packages/site-whole/src/assets/css/chat-widget.css —
   preserved as a code fork because its NJK, JS, and CSS all use the
   emma-* naming convention and cannot be easily reconciled without
   rewriting all three layers.

   Theme contract (override any of these in the consuming site):
     --chat-primary      Primary accent (FAB, user bubble, buttons)
     --chat-primary-deep Hover / pressed state for --chat-primary
     --chat-primary-glow rgba() focus-ring / outer pulse tint
     --chat-on-primary   Foreground for text on primary background
     --chat-ink          Body text / message text color
     --chat-charcoal     Header background
     --chat-warm         Messages area background
     --chat-mist         Muted text (status, placeholder)
     --chat-cloud        Input borders / dividers
     --chat-white        Surface / panel background
     --chat-radius       Panel corner radius
     --chat-font         Primary font family for the widget

   Defaults below use the green theme (4 of 5 sites). site-term
   overrides to navy/gold; see packages/site-term/src/css/main.css.
