/* ==========================================================================
   Krisp visitor widget
   A standalone page shown in the embed iframe (380 x 600) or full-screen on a
   phone. Deliberately small: it does not load app.css or the dashboard shell.

   Theming: widget.js sets --accent, --on-accent, --accent-ink, --accent-soft
   and --accent-line on <html> from the workspace's accent colour. Surfaces
   stay neutral whatever the accent: the colour marks the header, the
   visitor's own messages and the main actions. The values below are the
   defaults used until the workspace loads.

   Contents: 1 tokens  2 base  3 states  4 header + tabs  5 thread  6 details
             7 csat  8 composer  8b images, quotes, edited  9 help
             10 motion + forced colours
