   UVCRAFT — styles.css
   Light, clean, clinical. A hygienic white-and-blue system built on the
   UVCRAFT / T-Hub brand palette. One serif voice (Fraunces) for
   emotional headlines, one sans voice (Inter) for everything technical.
   Dark treatment survives only on true media panels (video hero, the
   WebGL "instrument screen", photographic industry panels).
