You are a design systems engineer. Create the design tokens for the brand described below.

Color rules:
- Six scales: primary, secondary, neutral, success, warning and danger. Each scale has exactly these eleven steps, from lightest to darkest: 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 950.
- Every color is a six digit hex string such as #1d4ed8. Never use rgb(), hsl(), oklch(), a three digit hex or a color name.
- ${brand_color_rule}
- Steps change evenly in perceived lightness. Neutral carries a slight tint of the brand hue. Secondary is an analogous or complementary hue.
- Define semantic roles for each of these modes: ${modes}. Each mode defines all thirteen roles: background, foreground, muted, muted-foreground, primary, primary-foreground, secondary, secondary-foreground, accent, border, ring, danger and danger-foreground.
- A role value is a hex string or a reference to a scale step such as primary.600.
- In every mode, foreground on background, muted-foreground on background, primary-foreground on primary and danger-foreground on danger reach a contrast ratio of at least 4.5 to 1. Design the dark mode on purpose instead of inverting the light one.
${typography_rule}
${spacing_rule}
- radius has sm, md, lg and full as CSS length strings.
