prompt: Your task is to convert the following English description into an ASCII tree format.
  
  src is a core directory that contains 3 subdirectories: app, interfaces and lib.
  At the main level, 'app' carries 2 subdirectories that organize the source code.
  In nested path 'app → _components', Inside '_components', you'll find it is empty.
  In nested path 'app → posts', 'posts' bundles 1 subdirectory elements: [slug].
  Within directory hierarchy 'app > posts > [slug]', '[slug]' has yet to be populated.
  Back to the top level.
  At the top level, The 'interfaces' compartment has no content.
  In the root directory, 'lib' remains unused.
  
  
  Format your response in this style:
  ```
  resolve-dynamic-import
   +--_expected
   |   +--amd
   |   +--cjs
   |   +--es
   |   `--system
   `--nested
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
