   Design system — Jardín de Mariposas La Paz
   Fase 3: Identidad visual editorial de alto nivel.

   THESIS: Un mariposario rural real donde la fotografía y el video son el
   producto; el diseño es soporte editorial silencioso, cálido y natural.
   No es una plantilla turística. Es una publicación digital de naturaleza.

   PALETTE: Bosque nuboso profundo + tierra + naranja de mariposa.
   NO cream/beige AI default. Cool mist green-white, not warm paper.
   TYPE: Newsreader (display editorial) + Karla (body humano).
