/* ============================================================
   nm.css — shared tokens + chrome for the Neomanifold demo pages.

   Every value here is traced to the REAL product, not to a design doc:
     tailwind.config.ts:7-11  → the only 3 custom colors (panel/panelAlt/edge)
     globals.css              → has zero CSS variables; the app inlines raw
                                Tailwind classes, so they are resolved to hex here
     sessionStatus.ts:4-12    → session badge pairs (single source of truth)
     RightPanel.tsx:67-84     → the action-rail button colors
     CandlestickChart.tsx:25-41 → chart palette
   NOTE: docs/plan/frontend-design-foundation.md proposes a --bg/--primary token
   layer and Button/Badge/Card primitives. That plan was NEVER implemented (the
   doc itself says the design system is "전무"). Do not build from it.

   The product is dark-only: no light mode, no theme toggle, no `dark:` variant.
