Components / Charts
Three series at most. Green, deep green, dark green.
Charts inherit the typography rules — 1.5px stroke (matching icons), Geist 11 axis labels, mono captions. Series colors come from the green ramp: 500, 700, 300. No more than three lines on one chart; if you need a fourth, you need a different chart.

1.5px stroke matches the icon system. Charts speak the same line weight as the toolbar. Visual coherence is operational coherence.
