/* =============================================================================
   ClientZapp website assistant — floating launcher and chat panel.

   Companion to assist.js. Uses the brand tokens declared in site.css (--navy-*,
   --gold-*, --line, --shell, --radius, --shadow) so it inherits any palette
   change. Loaded by site/layout.blade.php after site.css; bump
   config/site.php → asset_version when this file changes.
