   NxTGen — Zen Session (immersive guided pre-trade routine)
   Additive to zen-upgrade.css. The overlay is intentionally
   always-dark (deep black/navy) regardless of light/dark theme,
   since it is meant to feel like a distinct focus environment —
   the rest of the app keeps its normal theme untouched.
