/* VPT-250 — styles of the example page and its floating call widget.
   The SDK itself ships no CSS (§8.44 D6): this file belongs to the example
   page, and an integrator copies it into their own project.

   Token values are a verbatim copy of the editor palette
   (editor/src/styles.css, ТЗ №113/№115: OKLCH, hue 286.98) — sdk/ must not
   depend on editor/, and the example page has no build step to import
   through. When the brand palette changes, this block is updated by hand.

   Tokens live on the .ht-demo / .ht-widget / .ht-call roots and never on
   :root: loading this file must not repaint the page it is embedded into.
   Every class carries the ht- prefix for the same reason. */
