4.0.1
Fixed OKLCH parsing, accepting both comma and space separated formats.
- Support CSS Color Level 4 space-separated syntax: oklch(40.1% 0.123 21.57)
- Continue supporting comma-separated syntax: oklch(70%, 0.15, 150)
- Alpha values in input are parsed but ignored (e.g., oklch(50% 0.1 180 / .5))
