+For pages SSR'd at the edge, we bundle them with the ESM version of Next in order to
+benefit from the better tree-shaking and thus, smaller bundle sizes.

+The absolute paths for _app, _error and _document, used in this loader, link to the regular CJS modules.
+They are generated in `createPagesMapping` where we don't have access to `isEdgeRuntime`,
+so we have to do it here. It's not that bad because it keeps all references to ESM modules magic in this place.
