   WP Flow Chatbot — modern, mobile-first chat UI (RTL)

   All sizes inside the widget are `em`-based with a fixed 16px base
   font-size on `.wp-flow-chatbot`, so host-theme root-font scaling
   can't break the layout. Colors come from CSS custom properties —
   per-flow `brand` overrides are applied as inline custom props.
