0.9.1-alpha.1

Patch Changes

• 09cda9d: Add the style engine, on the new @xaui/native/system subpath.

  createRecipe declares a component's style once and resolves it in two passes. The cached pass is keyed by finite tokens alone — theme, mode, variant, the axes, the active states — so StyleSheet.create runs once per combination for the app's lifetime and every slot reads a stable reference, which is what lets React.memo work and keeps a press from allocating. The color prop takes arbitrary values, so it stays out of the key and gets a second, uncached pass: the cache grows with the number of token combinations, not with the palette an app invents.

  A variant names tokens and a single paint function says where they land, so the tint pass reuses it and color lands wherever the variant put its tokens — a background for primary, a label for ghost, a border for tertiary — with nothing further to declare. theme/derive-tint.ts expands one raw tint into the six slices a variant consumes, using the same OKLab formulas as the derived colour layer, memoized per tint and mode.
