To create a design system with semantic and literal color tokens, define a two-layer token mapping where semantic references point to literal values. This enforces consistent visual meanings across components instead of raw hex values.

Establishing spacing and typography scales requires defining mathematically consistent spacing increments and ratio-based typography sizes. These scales ensure downstream interface specifications maintain bounded, reusable layout and text proportions.

You need to define UI design tokens when starting a new frontend project, when component specs reference non-existent token names, or when generated UI shows inconsistent visual values like mismatched paddings or raw colors.

Prevent inconsistent visual values and silent defaulting by gathering required theme, brand, and density inputs upfront. This pre-flight setup ensures the token vocabulary aligns with direction before generating interface specifications.

Yes, you can define both light and dark theme tokens using a two-layer mapping. Semantic tokens reference different literal values based on theme requirements, allowing components to switch themes without changing token names.

A design system foundation should include explicit breakpoints for layout rules, bounded border radius sets, and defined elevation scales. These establish consistent structural visuals for downstream component generation.
