prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  [lang]
   +--@modal
   |   +--(.)feed
   |   `--(.)photos
   |       `--[id]
   +--feed
   `--photos
       `--[id]
  ```
  
  Convert this description:
  
  app is a core directory that features 8 subdirectories. Notable ones include bound-args, error, fallback-params among others.
  
  Let me break down the layout for you:
  
  In the root directory, 'bound-args' is currently empty.
  At the top level, The 'error' storage space is blank.
  At the top level, 'fallback-params' groups 1 subdirectories: [slug].
  At level 2, in directory path 'fallback-params > [slug]', '[slug]' sits empty.
  At the top level, Inside 'search-params', you'll find it is blank.
  At the main level, 'search-params-caught' lacks any subdirectories.
  At the top level, 'search-params-unused' has yet to be populated.
  At the top level, Inside 'uncached-promise', you'll find it has no folders inside.
  At the top level, Inside 'uncached-promise-nested', you'll find it holds no subdirectories at the moment.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
