/* ============================================================
   Strategy Copilot — product tokens ("precision instrument panel")
   Copilot always renders <html data-theme="light|dark"> (App.razor; light unless the viewer picked dark), so these
   html[data-theme] blocks outrank the TradeScan defaults above. Warm-grey neutrals, one deep ink-blue primary, green/red only
   for P&L and Buy/Sell, amber for warnings. Every text colour here is ≥ 4.5:1 on --bg-surface and --bg-primary.
   Fonts are self-hosted (CSP font-src 'self'); OFL licences sit next to the files in /fonts.
