/* app.css — ZK Group BoD Dashboard.
 *
 * Architecture is ported from deliverables/bod-dashboard/prototype/ — the same
 * views, filters, KPI grammar and status vocabulary. What changed is the brand:
 * the prototype's navy/gold is replaced by the group's own black on white.
 *
 * Every colour is a token or a color-mix() of tokens. No literals.
 * Black means "look here", never "bad". There is no accent hue at all.
 * English, LTR.
