   Cyber Arena Venezuela — Estilos base
   Sistema de diseño:
     - Fondo carbón/negro mate con superficies "glass" translúcidas.
     - Acento bronce mate (tomado del isotipo) + un único acento neón
       cian-verde, usado con moderación (estados, brillo de progreso).
     - Tipografía: Chakra Petch (títulos, técnica/HUD) + Manrope (cuerpo).
     - Motivo visual recurrente: la retícula/radar del logo, como
       separador de secciones en vez de líneas genéricas.
