/*
 * Brandfine widget styles — public-site CSS.
 *
 * Design goals:
 *   1. Theme-agnostic. Every selector is scoped under
 *      `.bf-widget` so we never bleed into the host theme,
 *      and we explicitly reset properties the theme might
 *      have inherited (font-size, line-height, box-sizing,
 *      color, text-align) so the widget looks the same on
 *      Twenty Twenty-Four, Astra, Divi, Elementor, etc.
 *   2. Customisable. Every colour, radius, and font size is
 *      a CSS custom property — customers override by writing:
 *        .bf-widget { --bf-color-primary: #ff6b00; }
 *      No theme override file needed.
 *   3. Light + dark. Defaults to a clean light look; respects
 *      `prefers-color-scheme: dark` for sites that don't pin
 *      a colour scheme. Customers who want strict-light or
 *      strict-dark override the variables themselves.
