     so the existing class rules keep working. Change a value in
     tokens.css and the whole page follows.

     Design language: clinical-instrument. Brand blue/cyan, used with
     discipline (gradient reserved for the orbit ring + primary CTA),
     equipment/CMMS data set in mono, the broken orbit ring as the
     signature motif (hero centerpiece + eyebrow mark).
