/*
  Antares Techno Park — hoja de estilos única.

  DECISIÓN TIPOGRÁFICA:
  El specimen de marca (files/03_Types/Types_Antares.pdf) sugería Halfre para
  titulares, pero al comparar las letras del mockup de referencia
  (01_BannerPrincipal02(2).pdf) contra ambas familias, "ANTARES" en la
  referencia tiene una A de remate plano y una R de pierna recta — coinciden
  con Causten, no con Halfre (que tiene una A de pico). Por eso todo el sitio
  usa una sola familia, Causten, en 4 de sus 18 variantes (para no penalizar
  performance):
    Black      → H1 del hero y todos los H2 de sección
    ExtraBold  → "eyebrows" (etiquetas pequeñas en mayúsculas) y títulos de tarjeta
    SemiBold   → nav, botones
    Regular    → párrafos, checklist, formulario
  Halfre no se usa en ningún lugar del sitio. Helvetica Neue queda solo como
  fallback del stack, nunca se carga como webfont.
