/* ==========================================================================
   KLINEA — Clinical Intelligence Platform
   Clinical-editorial system: paper-white ground, hairline rules as
   structure. One family (Hanken Grotesk — the product's own UI type),
   weights doing the hierarchy; Spline mono strictly for data.
   Color is committed, not decorative: one deep-teal band, solid teal
   actions, zero glows and zero gradients.
