  subpath-imports-nested is a head directory that bundles 2 subdirectories: input and output.
  At the top level, 'input' maintains 1 contained folders: nested.
  In nested path 'input > nested', 'nested' has been left empty.
  Back to the top level.
  In the root directory, 'output' remains unused.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
