   |   `--_expected
   `--simplify-non-boolean
  ```
  
  Convert this description:
  
  surfsense_browser_extension is a central directory that holds 5 subdirectories. Notable ones include assets, background, lib among others.
  
  The project source code seems to be organized in the 'lib' repository.
  
  Let me break down the construction for you:
  
  At the main level, 'assets' is devoid of content.
  At the top level, 'background' comprises 1 directories: messages.
  At level 2, in directory path 'background / messages', 'messages' is barren.
  In the root directory, The 'lib' data structure is empty.
  In the root directory, 'routes' possesses 2 directory entries: pages, ui.
  At level 2, in directory path 'routes → pages', 'pages' appears to be unused.
  At level 2, in directory path 'routes → ui', The 'ui' data structure holds no subdirectories at the moment.
  At the main level, Inside 'utils', you'll find it is vacant.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
