/* ===========================================================================
   Conversational chat widget — TwinFold styling
   ===========================================================================
   Every selector is scoped under #tfc-chat and every class carries the
   tfc-chat- prefix, so a docked widget that renders on every page cannot bleed
   into the theme around it. There are deliberately no html/body rules.

   Palette follows static/css/legacy-form.css (brand blue #0c5081, accent
   orange #f05a2b, pill buttons, soft cards) so the widget reads as part of the
   site rather than as a third-party embed. Blue carries the chrome — launcher,
   header, the visitor's own bubbles — and orange is reserved for the single
   primary call to action at the end of the conversation.

   The brand colour is exposed as both a hex and an "r, g, b" triple: the
   launcher shadow, the attention pulse and the choice-button hover all need it
   at partial alpha, and the reference sheet hardcoded the colour in those five
   places, which is exactly how a rebrand ends up half-finished.

   Behaviour lives in static/js/chat-funnel.js; markup in
   templates/partials/chat_funnel.html.
