/* =========================================================
   PLENOX FIXTURE — token system
   Light theme, rooted in the real plenox.ai palette (navy /
   teal / orange on white) but retuned for a data-dense console:
   neutrals cooled toward navy, three reserved status hues
   (ok / warn / critical) that are never used decoratively.
   Type: Inter, single family, weight-driven hierarchy.
   Shared by the landing page and the operations simulation.
