   Plug and Play — Mentor Network
   Design system matches the PTA/PAA and IT Park proposal decks:
   navy foundation (#253B49), purple (#6C6CD0) + yellow (#F0E545)
   accents, Protipo type.

   Drop the 6 Protipo-*.otf files into assets/fonts/ to activate
   the real brand font. Everything already works with the
   fallback stack until then — nothing breaks if they're missing.
