/* G-Strata Instruments · sistema "liquid glass" común a todo el sitio
   (inicio, SEMq-1, G-SID, Ciencia y Validación, Reconocimiento y Ferias).
   Se carga al final de cada página. Botones de cristal que sobresalen y se tiñen al tocarlos,
   paneles esmerilados tipo dashboard que se elevan, y un menú de pestañas idéntico en todas las páginas.
   Sin saturate, sin brillos animados y sin halos cian. */
