Release historycaution

The package has four releases over about seven years and none in the last three years, which suggests a slow maintenance cadence. The active DefinitelyTyped repository provides meaningful compensating evidence for continued project maintenance.

Repo package mentioncaution

The linked repository does not match the package name and its README does not mention the package, creating some uncertainty about repository association. Its use as a DefinitelyTyped monorepo is a partial explanation but does not remove the mismatch entirely.
