v11.5.0

Minor Changes

• #1319 dccf2af Thanks @lukasoppermann! - Add z-index design tokens for managing stacking context. Introduces base z-index scale (0-600) and 8 semantic functional tokens: behind, default, sticky, dropdown, overlay, modal, popover, and skipLink. Includes LLM metadata with usage guidance and shadow-to-z-index alignment rules.

• #1315 8bb3e76 Thanks @lukasoppermann! - Add some missing tokens that confused the AI

• #1320 6c1af22 Thanks @lukasoppermann! - Add negative base size tokens (negative-2 through negative-48) for sizes 2–48

Patch Changes

• #1301 423b6e1 Thanks @lukasoppermann! - Convert duration tokens to w3c

• #1318 4d0f257 Thanks @lukasoppermann! - Fix dark mode contrast for controlTrack and controlKnob tokens. The track now recedes (darker) and the knob stands out (lighter) in all dark mode variants, fixing the inverted visual hierarchy in SegmentedControl and ToggleSwitch.

• #1308 135dd9b Thanks @lukasoppermann! - Update shadow tokens to use W3C DTCG object format for dimension values

  • Shadow token dimension properties (offsetX, offsetY, blur, spread) now use object format { value: number, unit: "px" } instead of legacy strings like "1px"
  • Updated shadowToCss transformer to handle W3C dimension objects
  • Updated ShadowTokenValue type to require DimensionTokenValue for dimension properties
  • Legacy string format for shadow dimensions is no longer supported

• #1306 e4e355f Thanks @lukasoppermann! - Adding metadata for:

  • shadow tokens
  • display tokens
  • ansi colors
  • syntax colors

• #1305 305c559 Thanks @lukasoppermann! - Change dimension tokens to W3C DTCG format (breaking change)

  • The transformers dimensionToRem, dimensionToRemPxArray, and dimensionToPixelUnitless now only accept W3C DTCG object-format dimension tokens. Legacy string-based dimension values are no longer supported and will throw errors.
  • In the W3C DTCG format, only px and rem units are supported. Support for em units has been removed.

• #1302 d5a7908 Thanks @lukasoppermann! - Improve context for agents
