/* ============================================================
   TRADE ZENITH — DESIGN SYSTEM
   Concept: "Celestial Navigation"
   — Zenith is the point directly overhead, the fixed
     reference used to navigate. The brand sits at that point:
     a guiding star for traders.
   — Visual language: obsidian night sky, starlight gold,
     hairline coordinate grids, a single apex light.
