These guides target the 3.2.0-rc.2 release candidate. It is a prerelease; check the release record and qualify your application before rollout. Generated from the installed, version-pinned 3.2.0-rc.2 TypeScript declarations. Signatures, overloads and JSDoc are taken from the package; private class members are omitted. Declaration links point to version-pinned package files.

These are Forma's optional compatibility classes, not native browser APIs or a claim that a TC39 proposal has shipped. Import this subpath explicitly.
