/* =========================================================================
 * SEARCH-UX polish — autosuggest dropdown + matched-term highlighting +
 * source badges + per-regulator deep-dive modal. Added 2026-05-28.
 *
 * Highlighting uses <mark class="hi"> nodes created via createElement —
 * the cool-paper aesthetic ports a warm-brass background so it stays
 * legible (contrast ≥ 4.5:1 with ink on brass-50% per WCAG AA).
