prompt: Your task is to convert an English description into an ASCII tree format using this style:

   |   `--src
   |       +--hello
   |       |   +--cpp
   |       |   `--headers

   `--tests
  ```
  
  Convert this description:
  
  app is a core directory that bundles 9 subdirectories. Notable ones include (group), client-ref-dependency, font among others.
  
  Let me break down the architecture for you:
  
  At the main level, '(group)' hosts 3 subdirectories: blog, dynamic, static.
  In nested path '(group) / blog', Inside 'blog', you'll find it contains nothing at present.
  In nested path '(group) / dynamic', 'dynamic' incorporates 1 child directories: [size].
  In nested path '(group) > dynamic > [size]', The '[size]' collection has been left empty.
  In nested path '(group) > static', Inside 'static', you'll find it has yet to be populated.
  Back to the top level.
  At the main level, 'client-ref-dependency' is a vacant space.
  In the root directory, Inside 'font', you'll find it contains nothing at present.
  In the root directory, The 'gsp' container is an empty container.
  In the root directory, The 'lang' repository appears to be unused.
  At the top level, 'metadata-base' features 1 directories: unset.
  At level 2, in directory path 'metadata-base / unset', 'unset' lacks any subdirectories.
  At the top level, 'route-config' is unpopulated.
  At the main level, 'sitemap-image' is barren.
  At the main level, 'sitemap-video' appears to be unused.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
