/* =========================================================================
   Libafang online chat widget (2026-09-22) — self-contained stylesheet.
   Reuses the theme custom properties from main.css; loaded site-wide only
   while the chat widget is enabled. FAB sits in footer.php's .float-tools
   column, the panel anchors above it (JS sets the exact bottom offset).
