/**
 * RNF Live Search v5.1 — Front CSS (complément)
 *
 * Ce fichier complète le CSS inline existant (header Astra) avec :
 *  - Effet fade du placeholder dynamique
 *  - Mode mobile collapsible (icône → barre déployée)
 *  - États supplémentaires du dropdown (vide, suggestion typo, loading)
 *  - Compatibilité avec les classes rnf-lsa__* existantes
 *
 * Si tu retires un jour ton CSS inline, ce fichier reste autonome.
