/* ============================================================
 * Axismundi — lab-search-bar.css
 * v3.5.8 — Search bar #17 Full-Spec + Runtime module
 *
 * Phase 2 scope:
 *   - Lab-only Search bar pattern scaffolding.
 *   - Runtime expansion layer derived from search-expansion/ evidence.
 *   - No baseline components.css §10 mutation.
 *   - No popover/ dependency.
 *   - Field host remains non-ripple; trailing icon buttons may consume Ripple v2.
