v0.3.0

Breaking changes

• ESM-only package ("type": "module"), no require() support.
• Public API is split into subpath exports:
  • @clhaas/palette-kit (runtime)
  • @clhaas/palette-kit/serialize (serializer)
  • @clhaas/palette-kit/export (exporters)
  • @clhaas/palette-kit/cli and bin palette-kit (CLI)
• Exporters are not re-exported from the main entrypoint to keep the runtime lean and tree-shakeable.

Features

• Public serializer (serializeColor, serializeResolved, theme.serialize) with OKLCH/sRGB/P3 output options.
• Public exporters: exportThemeCss (progressive @supports fallbacks) and exportThemeJson (stable { light, dark } structure).
• Declarative Token Registry + official token presets (minimal-ui, radixLike-ui, modern-ui).
• CLI tooling:
  • palette-kit init (typed config template)
  • palette-kit build (deterministic dist/palette/ artifacts: CSS/JSON/TS + d.ts)
• Strong inference and DX validation improvements (strict vs non-strict behavior, clearer errors).

Migration

• See docs/Migration.md for upgrade notes and updated import paths.
