/* ---------- FONTS ----------
   Evolvable runs three faces:
   1. ABC Camera     — display / all-caps H1 (distinctive, slightly geometric)
   2. Acumin Pro     — body, UI, buttons (Typekit kit mov4cer)
   3. Adobe Garamond Pro — italic editorial pull-quote (Typekit)
   We load Camera locally, and the two Adobe faces via Typekit. A safe
   sans + serif fallback is provided so designs still read well
   offline or if Typekit fails. */

     COLOR TOKENS
     Evolvable's palette is warm, airy, close-to-neutral.
     Surfaces are soft creams and sages; accents are cool teal.
     Black is used as a hairline — everything is outlined, never
     filled with heavy color.

     below ALREADY assume this. When lifting a token into a fresh
     page, set the same root size.
