/* =====================================================================
   Studappy · tema nocturno
   Inspirado en el video de presentación (azul noche, cartas del logo y
   marca en tipografía pixel), en versión sobria: brillos suaves, pocas
   animaciones y la letra pixel solo como acento.
   Se carga después de styles.css y solo cambia el aspecto visual.
