ESM-only: "type": "module" with no CommonJS build, so it is loaded with import. require() of it resolves only on Node 22.12+, which supports require(esm).

What This Package Does

Provides the canonical type definitions used across all Rebase packages — both client-side and server-side. This is a types-only package with no runtime dependencies. Every other @rebasepro/* package depends on it.
