/* ============================================================
   CASE STUDY "Funnel di selezione" - /laboratorio-funnel-selezione
   Due parti:
   - pagina (.fs-*): numeri chiave, testo, snippet SQL, video
   - dashboard (#fs-dash): adattata dall'originale (Archivo + toni
     viola) ai font e ai blu del sito. Tutto e' sotto .fs-dash, cosi'
     classi generiche come .panel o .table non toccano il resto del sito.
   Il sito e' solo in tema chiaro: niente varianti dark.
