// `whenexpr` is runtime-only bundled (see `onlyBundle` below); its
// declaration file mixes type-only and value named exports
// (`export { type WhenExpression, evaluateWhen, ... }`) in a way that
// trips up rolldown's dts bundler when it tries to inline the type
// graph too (spuriously drops the `type` modifier off the merged
// re-export, then can't find `WhenExpression` as a value export). Leave
// `whenexpr`'s types external and let dts consumers resolve them
// straight from the published package.
