cn is a new engine for Tailwind class merging and conflict resolution. It replaces tailwind-merge and clsx. Same APIs. Full parity. And it is 30× faster.

Our verdict: not recommended
Drop-in for tailwind-merge+clsx, 320 ns to 10 ns per common call (its own bench). Real but no visible gain on marketing sites; keep tailwind-merge.
