color-mix() resolved at compile time by lightningcss can yield NaN chromaticity channels for degenerate mixes (e.g. mixing black with transparent in oklab). Passing NaN to colorjs.io produced an invalid color string like "#NaNNaNNaN80" that React Native silently discards, so utilities such as Tailwind's bg-black/50 rendered with no background. Treat NaN channels as 0 (a missing component per CSS Color 4) for the lab/lch/oklab/oklch cases, so the example resolves to nativewind#80. Fixes nativewind#317
