prompt: Your task is to convert the following English description into an ASCII tree format.
  
  _expected is a origin directory that gathers 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the ordering for you:
  
  At the main level, 'amd' encapsulates 1 folders: custom.
  In nested path 'amd > custom', Inside 'custom', you'll find it is blank.
  At the top level, 'cjs' hosts 1 subdirectory elements: custom.
  In nested path 'cjs / custom', The 'custom' container is vacant.
  Back to the top level.
  At the main level, 'es' has 1 subdirectories: custom.
  At level 2, in directory path 'es > custom', 'custom' is devoid of content.
  At the top level, 'system' has 1 subdirectory elements: custom.
  In nested path 'system → custom', Inside 'custom', you'll find it has no folders inside.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  app
   +--(bar)
   |   `--bar
   `--(foo)
       `--foo
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
