   Claude Window — vanilla embed for wassenger.com
   ============================================================
   Drop this CSS once on the page, then mark up any container
   with class .claude-window and pair it with claude-window.js
   for the auto-animation when scrolled into view.

   Self-contained — no external dependencies. Uses system fonts
   (SF Pro Display on Apple devices, fallbacks elsewhere) so no
   Google Fonts request is required.
