/* =========================================================
   KPS Portal — Glass Design System
   Palette pulled from the KPS star-and-book emblem.
   Two glass registers:
     - "ink glass"   : dark, translucent, on the navy mesh (header/sidebar/hero/footer)
     - "frost glass" : light, translucent, sits on top of the mesh (content cards)
   Signature motif: the emblem's eight-point star, reused as a
   quiet recurring mark (nav bullets, section dividers, card corners).
