/**
 * Website AI Assistant — chat styles (floating widget + inline panel,
 * plus every component the embedded version shares).
 *
 * Every colour, font and radius is read from the Chimney Smart theme tokens
 * declared in themes/chimney-theme/css/main.css. The literal values after each
 * var() are fallbacks so the plugin still renders sensibly if the theme changes.
 *
 * Themes: .wsai-theme-light (default) and .wsai-theme-dark, set on every root
 * element by the PHP templates from the Style setting (or a shortcode attribute).
