/**
 * AI Search Box block styles.
 *
 * Two rules govern this file:
 *
 * 1. Colour comes from the theme. Every visible colour is either the
 *    theme's own custom property or a translucent grey that adapts to
 *    whatever sits behind it, so the box never looks imported from
 *    another site - and dark themes work without a media query.
 * 2. Only structure and state live here. No decorative flourishes that
 *    would fight the theme's own visual language.
 */

/* Tokens: one place to retune the whole block, and the fallbacks keep
   classic (non block) themes looking deliberate rather than unstyled. */
