/* estilos/corriente.css — Identidad "Corriente DC" (va después de profesional.css).
   La C del logo está hecha de pistas de circuito y DC es corriente directa: la interfaz es sobria, pero una

   Movimiento con propósito: solo transform/opacity/stroke (60 fps) y nada si el equipo pide reducir movimiento. */
