   BioScience Prime Labs — Laboratory environment design layer
   Loaded AFTER main.css.

   Reads as a clean room, not a printed spec sheet: cool clinical
   surfaces tinted from the client palette, diffuse overhead-light
   shadows, softened glassware geometry, generous space.

   Every surface, border and shadow below is derived from the six
   brand blues (#002242 … #9DCAE1). No warm greys, no Tailwind slate.
