  In nested path '(auth-pages) > sign-in', Inside 'sign-in', you'll find it is a vacant space.
  In nested path '(auth-pages) > sign-up', 'sign-up' is an empty container.
  At the main level, 'auth' possesses 1 subfolders: callback.
  Within directory hierarchy 'auth > callback', 'callback' is devoid of content.
  Back to the top level.
  In the root directory, 'protected' comprises 1 subfolders: reset-password.
  In nested path 'protected / reset-password', The 'reset-password' folder holds no subdirectories at the moment.
