   ARPANIA — Brand Token System
   Sourced directly from the Arpania case-study deck & logo:
   - Red DB2128, Charcoal 1A1A1A / panel 373E44, Navy 1F3A52
     (navy reserved for phase/section dividers, as in the deck)
   - Display: Playfair Display (bold serif headlines — matches
     the deck's "Strategic Management Consulting" treatment)
   - Body: Inter. Kickers: Inter, bold, uppercase, letter-spaced,
     in red — exactly as used throughout the deck.
   Signature: the diagonal red cover panel, carried from the
   deck's title slide into the hero and CTA.
