prompt: Your task is to convert the following English description into an ASCII tree format.
  
  app is a source directory that collects 3 subdirectories: (blog), (sanity) and api.
  In the root directory, '(blog)' incorporates 1 folders: posts.
  Within directory hierarchy '(blog) → posts', 'posts' shelters 1 directories: [slug].
  Within directory hierarchy '(blog) / posts / [slug]', The '[slug]' collection remains unused.
  In the root directory, '(sanity)' retains 1 child directories: studio.
  Within directory hierarchy '(sanity) → studio', 'studio' houses 1 contained folders: [[...tool]].
  In nested path '(sanity) → studio → [[...tool]]', '[[...tool]]' has yet to be populated.
  Back to the top level.
  At the main level, 'api' organizes 1 contained folders: draft-mode.
  In nested path 'api → draft-mode', 'draft-mode' shelters 1 nested folders: enable.
  Within directory hierarchy 'api > draft-mode > enable', The 'enable' data structure is empty.
  
  
  Format your response in this style:
  ```
  custom_resolve_dir
   +--testproj
   |   `--__snapshots__
   `--testproj2
       `--__snapshots__
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
