(e.g. Taillwind's rgb(r g b / var(--tw-opacity)))
- css-engine/schema: extend ColorValue.alpha to number | VarValue
- css-engine/to-value: serialize VarValue alpha using toValue()
- css-data/parse-css-value: add parseColorWithVarAlpha using css-tree
AST substitution (no fragile string replacement); inject fallback: 1
when var has no explicit CSS fallback
- style-object-model: resolve VarValue alpha in substituteVars so the
color picker receives a number when the custom property is defined
- color-control: use VarValue.fallback for the picker when alpha is
still unresolved, falling back to 1 only as a last resort
