prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  main
   +--java
   |   `--com
   |       `--example
   |           `--worker
   `--resources
       `--META-INF
           `--gradle-plugins
  ```
  
  Convert this description:
  
  preview-fallback is a central directory that assembles 2 subdirectories: pages and test.
  At the top level, 'pages' holds 3 subdirectories: api, fallback, no-fallback.
  In nested path 'pages / api', 'api' holds no subdirectories at the moment.
  Within directory hierarchy 'pages > fallback', Inside 'fallback', you'll find it contains no subdirectories.
  At level 2, in directory path 'pages / no-fallback', Inside 'no-fallback', you'll find it has been left empty.
  At the main level, 'test' has been left empty.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
