@phpstan-template-contravariant

The @phpstan-template-contravariant tag is PHPStan's vendor-specific @template-contravariant alias. It is the vendor-prefixed spelling of @template-contravariant, which this component already recognizes bare.

This library recognizes it as an alias: it parses identically to the canonical tag above and produces the exact same tag instance, keeping the vendor-prefixed name it was written with.

PHPStan's generics variance page covers contravariance conceptually, though it doesn't spell out this prefixed tag literally.
