  switchable-runtime is a central directory that holds 3 subdirectories: app, pages and utils.
  In the root directory, 'app' features 8 subdirectories that organize the source code.
  In nested path 'app → app-invalid-runtime', Inside 'app-invalid-runtime', you'll find it is vacant.
  Within directory hierarchy 'app > app-valid-runtime', 'app-valid-runtime' has no content.
  Within directory hierarchy 'app / edge-rsc', 'edge-rsc' is currently empty.
  Within directory hierarchy 'app → legacy-extension', Inside 'legacy-extension', you'll find it is barren.
  In nested path 'app > node-rsc', Inside 'node-rsc', you'll find it appears to be unused.
  In nested path 'app → node-rsc-isr', The 'node-rsc-isr' collection contains nothing at present.
  Within directory hierarchy 'app / node-rsc-ssg', 'node-rsc-ssg' has no folders inside.
  Within directory hierarchy 'app / node-rsc-ssr', Inside 'node-rsc-ssr', you'll find it awaits content.
  In the root directory, 'pages' incorporates 2 directories: api, edge.
  Within directory hierarchy 'pages / api', The 'api' directory has been left empty.
  In nested path 'pages > edge', Inside 'edge', you'll find it hasn't been filled with any content.
  Back to the top level.
  In the root directory, The 'utils' data structure is empty.
