/* ==========================================================================
   DioptriFit · Liquid Glass — mismo lenguaje que cierre-caja-liquid-glass.css
   y citas-liquid-glass.css: vidrio real solo en el panel y la cabecera,
   ambiente de color por gradientes detrás, barrido especular, tarjetas
   uniformes translúcidas y curva de resorte en todo lo interactivo.
   Siempre activo (no depende de ?boceto=glass). Todo va colgado de
   #dioptrifit-overlay para que no se escape a ninguna otra pantalla.

   El escenario de la foto se queda deliberadamente oscuro: una imagen
   clínica se juzga mejor sobre fondo neutro oscuro, y el contraste de los
   puntos de color depende de ello.
