Design Token Theming

Status: READY

Purpose

Define reusable colors, spacing, typography, and component states so interfaces stay consistent under iteration.

Standards

• Use semantic tokens instead of hard-coded colors.
• Support light, dark, and system mode.
• Respect WCAG AA contrast and reduced-motion preferences.
• Keep component states explicit: default, hover, focus, active, disabled, loading, empty, and error.

Workflow

1. Define color, spacing, typography, radius, and shadow tokens.
2. Map tokens to components and page patterns.
3. Verify contrast, focus visibility, and touch-target size.
4. Validate screenshots in light and dark contexts before approval.

Evidence

• Token file or theme contract exists.
• All primary UI surfaces work in light and dark mode.
• Contrast and focus are verified in QA.
