/* =============================================================================
   billchat.css — "Chat with @dollarbill" live-chat POPUP for the /users hub
   (THE PRINCE OF PROXY). A faithful clone of fragchat.css (same component/UI),
   scoped under .bc-* / #bc* so it can never collide with fragchat's .fc-* or
   usernames.css. Every colour is drawn from the shared theme.css palette so it
   re-themes for free across wtf / dark. Motion is transform/opacity only and is
   disabled wholesale under reduced-motion.

   AVATAR. @dollarbill has NO staged avatar yet, so the launcher/header/gate use
   a tasteful 👑 CREST monogram (the "Prince of Proxy" mark) drawn in CSS — swap
   .bc-crest for a real <img> once an avatar is staged.
