   Nexus HCM — Sistem Identiti Visual (Fasa 3)
   [CHANGE] what: design-system foundation — tokens + reusable .nx-* components
            · why: brand identity approved 2026-07-24 (corporate navy/brass/serif)
            · verify: link on any page, inspect --nx-* vars + .nx-* classes render
   Static, build-free CSS. The single source of truth for the identity —
   every screen skins against these tokens. Colours, type and the ledger
   figure treatment match the approved preview exactly.
