prompt: Your task is to convert the following English description into an ASCII tree format.
  
  vary-header is a core directory that houses 2 subdirectories: app and test.
  At the main level, 'app' keeps 2 subdirectories that organize the source code.
  In nested path 'app / app', Within 'app', you'll find 1 child directories for code structure.
  At level 3, in directory path 'app > app > normal', 'normal' has been left empty.
  In nested path 'app / pages', 'pages' stores 1 nested folders: api.
  In nested path 'app → pages → api', The 'api' storage space is an empty container.
  Back to the top level.
  At the top level, Inside 'test', you'll find it appears to be unused.
  
  
  Format your response in this style:
  ```
  gradle
   +--api
   |   `--plugins
   |       `--catalog
   |           `--internal
   `--catalog
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
