    // tsup's bundled rollup-plugin-dts injects `baseUrl: "."` into the
    // compiler options it builds for .d.ts generation (rollup.js ~6837).
    // TS 6 deprecates baseUrl and errors on it (TS5101), which fails the
    // dts step even though nothing here sets it. Silencing is safe: we do
    // not use baseUrl or paths, so the injected value resolves nothing.
    // Remove this once tsup ships a plugin that stops injecting it.
