/*!
 * Search+ 3.0 — facet chips inside the search overlay (CONTRACTS-WAVE2 §3).
 * Companion of assets/js/sp-facets.js. Budget: this file <= 6144 bytes.
 *
 * Loaded AFTER search-plus.css (a declared dependency) and reusing its tokens,
 * so a theme that re-tints the overlay re-tints the chips. Every token carries a
 * literal fallback in case only this stylesheet loads.
 *
 * Every selector carries two classes on purpose: the overlay's defensive reset
 * (`.sp-root *` — border: 0, background: none, outline: 0, animation: none)
 * has one-class specificity, so anything single-class here would lose to it.
