   NATIV 2027 — Design system
   Paleta oficial del brandbook de Nativ:
   índigo #3f3897 (marca/autoridad), cian #8be0f2 (acción/highlight),
   azul marino #2b2a59 (fondos oscuros), grises fríos de marca
   (#f2f6fa / #d8e0e8 / #c8d0d9 / #5c87a6 / #313c51).
   Colores secundarios de marca: menta #8ee4b2, amarillo #f9d153,
   rojo #ef374e — reservados para estados (éxito/alerta/error).
   Tipografía: Pangram (principal) — no incluida como webfont libre;
   se usa "General Sans" (Fontshare, geometría equivalente) como
   sustituto hasta licenciar Pangram. Montserrat (secundaria) sí
   está disponible vía Google Fonts.
