/* Prompt Box — styles for blockquotes upgraded to prompt boxes, and for an
 * image paired with the prompt that follows it.
 *
 * It reads the active theme's colour tokens (--cd-*), so the box matches the
 * theme in light and dark mode. Every token has a fallback, so the box still
 * looks right on a theme that does not define them. Override these from a
 * theme or Customizer CSS to restyle:
 *
 *   --bhpb-accent        button / selection colour  (default: the theme's primary)
 *   --bhpb-height        height of the prompt area on its own    (default 350px)
 *   --bhpb-pair-height   height of the prompt area under an image
 *                        in the one-column layout                (default 280px)
 *   --bhpb-pair-min      shortest a side-by-side pair may be     (default 27rem)
