/* ===== Floating chat heads =====
   Messenger-style avatar bubbles that appear on ANY page (not the chat page
   itself - static/website/js/chat-heads.js no-ops there) when a message
   notification arrives. Loaded on both frontend/website/base.html and
   frontend/dashboard/base.html, so every custom property below has an
   inline fallback rather than relying on either site's own theme variables.
