/* Prompt Box — styles for blockquotes upgraded to prompt boxes.
 *
 * Theme-agnostic on purpose: text colour is inherited and every tint is a
 * translucent grey, so it reads on light and dark themes alike. Override
 * these custom properties from a theme or Customizer CSS to restyle:
 *
 *   --bhpb-accent   button / selection colour   (default #2563eb)
 *   --bhpb-height   height of the prompt area   (default 350px)
