/* ─────────────────────────────────────────────
   PRDRWNDN CRM — Design System

   Palette drawn from the Rwandan flag itself rather than a generic
   admin-dashboard blue: deep sky blue field, sun yellow, and the
   green of the land, set against a warm off-black so the accent
   colors carry weight instead of competing with pure white/black.

   Display face: a confident geometric sans for headers (Space Grotesk)
   paired with a clean workhorse sans for body/data (Inter) — distinct
   roles, not the same family doing both jobs.
