   ------------------------------------------------------------------
   Estilos globales que usan TODAS las secciones:
     · Reset
     · Tipografía base
     · Formularios (inputs, textareas, selects)
     · Botones reutilizables (.btn, .btn-primary, .btn-ghost, etc)
     · Badges y texto con gradiente
     · Contenedor (.container) y header de sección
     · Scrollbar custom
     · Utilidades (.hidden, .gradient-text)

   Cada sección tiene su propio .css aparte para estilos específicos.
