prompt: Your task is to convert the following English description into an ASCII tree format.
  
  variable-engine is a master directory that gathers 2 subdirectories: variable-core and variable-layout.
  At the main level, 'variable-core' comprises 3 subdirectories: __mocks__, __tests__, src.
  In nested path 'variable-core / __mocks__', Inside '__mocks__', you'll find it has yet to be populated.
  In nested path 'variable-core > __tests__', '__tests__' houses 3 test-related directories.
  In nested path 'variable-core / __tests__ / ast', 'ast' organizes 1 directories: __snapshots__.
  Within directory hierarchy 'variable-core / __tests__ / ast / __snapshots__', '__snapshots__' is devoid of content.
  At level 3, in directory path 'variable-core → __tests__ → case-run-down', Inside 'case-run-down', you'll find it is unpopulated.
  At level 3, in directory path 'variable-core → __tests__ → scope', Inside 'scope', you'll find it is unpopulated.
  At level 2, in directory path 'variable-core > src', Within 'src', you'll find 5 subdirectories for code structure.
  In nested path 'variable-core > src > ast', 'ast' contains 5 several folders.
  Within directory hierarchy 'variable-core / src / ast / common', The 'common' data structure appears to be unused.
  Within directory hierarchy 'variable-core > src > ast > declaration', The 'declaration' compartment contains no subdirectories.
  Within directory hierarchy 'variable-core → src → ast → expression', Inside 'expression', you'll find it has no content.
  In nested path 'variable-core / src / ast / type', The 'type' data structure is currently empty.
  At level 4, in directory path 'variable-core → src → ast → utils', 'utils' has no content.
  In nested path 'variable-core → src → react', 'react' groups 1 directory entries: hooks.
  In nested path 'variable-core > src > react > hooks', 'hooks' is barren.
  At level 3, in directory path 'variable-core > src > scope', 'scope' maintains 1 subdirectories: datas.
  Within directory hierarchy 'variable-core / src / scope / datas', The 'datas' compartment has yet to be populated.
  At level 3, in directory path 'variable-core → src → services', The 'services' compartment is a vacant space.
  In nested path 'variable-core > src > utils', 'utils' is barren.
  Back to the top level.
  At the top level, 'variable-layout' retains 3 contained folders: __mocks__, __tests__, src.
  In nested path 'variable-layout > __mocks__', '__mocks__' has yet to be populated.
  At level 2, in directory path 'variable-layout > __tests__', '__tests__' organizes tests across 1 separate nested folders.
  Within directory hierarchy 'variable-layout → __tests__ → __snapshots__', The '__snapshots__' data structure is an empty container.
  At level 2, in directory path 'variable-layout > src', The 'src' section stores 2 folders for code organization.
  At level 3, in directory path 'variable-layout > src > chains', The 'chains' collection is a vacant space.
  Within directory hierarchy 'variable-layout > src > scopes', 'scopes' is empty.
  Back to the top level.
