  ENCA Services — Estilos complementarios a Tailwind CSS (cargado vía CDN en index.html).
  Este archivo cubre lo que las utilidades de Tailwind no resuelven directamente:
  tipografía base, header dinámico al hacer scroll, fondos con gradiente/patrón,
  animaciones de entrada y componentes repetidos (pills, tarjetas de valores/equipo/servicios).

  Paleta de marca:
    --color-primary  #2A3B4C  Azul Pizarra Profundo — menú, títulos, secciones de autoridad
    --color-accent   #006D77  Verde Petróleo — botones CTA y detalles dinámicos
    --color-smoke    #F5F5F5  Blanco Humo — fondo neutro del sitio
