/* ==========================================================================
   Noveqtech School Management — design system v2 ("Horizon")
   Three independent colour layers (see docs/DESIGN-SYSTEM.md):
     1. THEME   — surfaces, ink, brand/accent        → data-theme on <html>
     2. MODULE  — where you are (hue per sidebar area) → data-module / --mod
     3. STATUS  — the state of a record (ok/warn/bad/info/called)
   Rule: module hues never mean state; status colours never mean place.
