prompt: Your task is to convert the following English description into an ASCII tree format.
  
  src is a origin directory that gathers 3 subdirectories: app, cases and implementations.
  In the root directory, Within 'app', you'll find 1 subdirectories for code structure.
  Within directory hierarchy 'app > Benchmark', The 'Benchmark' collection is blank.
  At the top level, The 'cases' folder is barren.
  At the main level, 'implementations' stores 3 directory entries: emotion-css-func, emotion-css-prop, emotion-styled.
  In nested path 'implementations → emotion-css-func', Inside 'emotion-css-func', you'll find it is empty.
  At level 2, in directory path 'implementations > emotion-css-prop', The 'emotion-css-prop' collection is devoid of content.
  At level 2, in directory path 'implementations → emotion-styled', The 'emotion-styled' collection is unpopulated.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  app
   +--(bar)
   |   `--bar
   `--(foo)
       `--foo
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
