Design Token Management

Token Pipeline

Source of Truth

• Define tokens in JSON/YAML (platform-agnostic).
• Or define in Figma Variables and export.
• Single source, multiple outputs.

Transformation

Tokens → Style Dictionary → Platform outputs:

• CSS custom properties (web)
• Swift/Kotlin values (mobile)
• JSON (documentation, tooling)

Token Structure

{
  "color": {
    "brand": {
      "primary": { "value": "#2563EB", "type": "color" },
      "secondary": { "value": "#7C3AED", "type": "color" }
    },
    "semantic": {
      "text": {
        "primary": { "value": "{color.neutral.900}", "type": "color" },
        "secondary": { "value": "{color.neutral.600}", "type": "color" }
      }
    }
  }
}

Versioning

• Semantic versioning for token packages.
• Breaking changes: removing tokens, renaming tokens.
• Non-breaking: adding tokens, changing values.
• Changelog for every token update.

Multi-Brand

• Base tokens shared across brands.
• Brand-specific overrides as separate token files.
• Theme tokens (light/dark) as separate layers.
• Compose: base + brand + theme = final token set.
