/**
 * Digitalize Hub — Live Search dropdown styles.
 *
 * v3.9.0 — W2F-BSF (item 29).
 *
 * The spec suggested ~30 lines; this file ships ~150 lines because we
 * need: empty + loading + error states, keyboard-active focus styles,
 * spinner keyframes, a responsive cap on small screens, and explicit
 * fallback values for every CSS variable so the dropdown reads
 * correctly even before the theme's inline :root vars are emitted.
 *
 * Every color / radius / shadow uses the theme's CSS variables
 * (--bg-card, --border, --text, --text-muted, --accent, --radius,
 * --ease) so the dropdown inherits the user's Theme Options overrides
 * automatically. Dark mode just works because functions.php emits the
 * same vars under html.dh-mode-dark / body.dh-mode-dark.
