/* Design Scuole Italia — child "Formigine 2" · f2-search.css
 * Stile della palette "Trova tutto". 100% canonico al tema (Bootstrap Italia / DSI):
 * usa SOLO token reali del design system — raggi 4px (.modal-content/.btn) e 12px (.chip),
 * ombra nativa del modal, superfici #f2f6f9, hairline #d9dadb, muted #5c6f82,
 * accent blu istituto #0000f5, colori-sezione del menu per i badge tipo.
 * Nessuno "stondo" custom, niente backdrop-blur, niente pill 999px: solo gli stondi del sito.
 * v0.43: più grande/presente, close = X (round), riga attiva con accento blu, hint solo desktop.
 * GPU-safe (opacity/transform), prefers-reduced-motion aware, mobile = foglio a tutto schermo.
 *
 * Token nativi (bootstrap-italia.css / scuole.css):
 *   --radius-panel: 4px   (.modal-content{border-radius:4px})
 *   --radius-chip : 12px  (.chip{border-radius:12px;height:24px})
 *   --radius-ui   : 4px   (.btn{border-radius:4px})
 *   --shadow      : 0 2px 10px 0 rgba(0,0,0,.1)  (.modal-content) + elevated card token
 *   --hairline    : #d9dadb  (.card border)
 *   --surface     : #f2f6f9  (superficie chiara del tema)
 *   --muted       : #5c6f82  (.chip-label / testo secondario)
 *   --ink         : #19191a  (testo)   --accent: #0000f5 (blu istituto)
