/* ============================================================================
   design.css — AlgoTrading's design system, carried over
   (AlgoTrading/design-system/algotrading-dashboard/MASTER.md, DashboardService/wwwroot/style.css + fx.css).

   Loaded after app.css, so the shell overrides here win. Three parts:
     1. Tokens: palette (dark first, light measured for contrast), the --phase / --accent split, type,
        spacing, shadows, motion.
     2. Shell: the app frame (Components/Layout/AppShell.razor) in AlgoTrading's chrome, plus the
        effects background (data-fx = full | calm | off).
     3. Pages: AlgoTrading's components, scoped under .ds-page so they never collide with the chart
        terminal's own .btn / .chip / .badge rules.
   The chart terminal (.terminal) deliberately keeps TradingView's palette; see app.css.
