/* ============================================================
   Ordium Consulting - foglio di stile condiviso

   Idea guida: "ordine". Carta chiara e calda, inchiostro quasi
   nero, un solo accento (il teal del marchio), filetti sottili
   al posto di ombre e riquadri. Il blu notte compare solo nei
   momenti di chiusura (invito finale e footer).

   Caratteri:
   - Newsreader     titoli, voce autorevole ed editoriale
   - IBM Plex Sans  testo corrente
   - IBM Plex Mono  etichette, numeri, metadati
