/* ===================================================================
   Tessivant — shared stylesheet

   PALETTE, derived from the two core principles:

   TRUST → the ground. Deep navy (#0F2C4C), light enough to READ as
           navy rather than as black. The blue/competence association
           only operates if the viewer can see the hue. Kept
           desaturated to avoid the generic corporate blue every
           contractor and bank already uses.

   VALUE → the accent. Bronze, not gold. The metal of seals, plaques
           and survey markers — worth that is earned and weathered
           rather than shiny. One accent only, used sparingly.

   Neutrals are pulled toward the navy so nothing reads as default grey.
