v1.3.1

Patch Changes

• #87 b5eb888 Thanks @tenphi! - Fix splitHue exports dropping a per-color darkHue. A color that authored
  only darkHue (no light hue) referenced the theme's --{name}-hue var in
  both schemes, so the --{color}-hue declaration emitted in the dark block was
  never read and the dark hue was silently ignored. A color that authors a hue in
  either scheme now gets its own hue custom property in both, tracking the theme
  hue in the scheme it did not author, so the shared var() reference stays valid
  and runtime re-skinning still works. Affects both css({ splitHue: true }) and
  the Tasty token map.

  Also corrects the tone: 'max' / 'min' with a base documentation: the
  high-contrast variants are not exempt from the light-shift replay. They follow
  the same rule, and because their tone window is already the full range the
  replay reproduces the plain mapping unless the base itself sits asymmetrically
  across schemes — a mode: 'fixed' or contrast-solved base, for example. The
  behavior is unchanged; only the docs and changelog claimed otherwise.
