What did you do?

Configuration

import css from "@eslint/css";

export default [
	{
		files: ["**/*.css"],
		plugins: { css },
		language: "css/css",
		rules: {
			"css/selector-complexity": ["error", { maxTypes: 0 }],
		},
	},
];

/* eslint css/selector-complexity: ["error", { "maxTypes": 0 }] */

@keyframes fade {
	from {
		opacity: 0;
	}

	to {
		opacity: 1;
	}
}

What did you expect to happen?

No errors. Keyframe selectors should not be counted by maxTypes.

What actually happened?

4:2  Exceeded maximum type selector. Only 0 allowed.
8:2  Exceeded maximum type selector. Only 0 allowed.
