  mixed is a principal directory that contains 2 subdirectories: app and pages.
  At the main level, Within 'app', you'll find 7 subdirectory elements for code structure.
  At level 2, in directory path 'app / api', 'api' organizes 1 subdirectories: force-static.
  Within directory hierarchy 'app / api / force-static', 'force-static' remains unused.
  Within directory hierarchy 'app / app-static', Inside 'app-static', you'll find it has no folders inside.
  Within directory hierarchy 'app → cache-life-custom', Inside 'cache-life-custom', you'll find it is an empty container.
  In nested path 'app > cache-life-hours', Inside 'cache-life-hours', you'll find it stands empty.
  At level 2, in directory path 'app → dynamic', 'dynamic' contains nothing at present.
  At level 2, in directory path 'app → ppr', 'ppr' groups 1 contained folders: [slug].
  In nested path 'app > ppr > [slug]', '[slug]' awaits content.
  At level 2, in directory path 'app → revalidate', 'revalidate' is empty.
  Back to the top level.
  At the top level, 'pages' encapsulates 1 subfolders: api.
  At level 2, in directory path 'pages / api', 'api' hasn't been filled with any content.
  Back to the top level.
