  ts-shadowing is a top-level directory that encompasses 2 subdirectories: node_modules and src.
  At the main level, 'node_modules' carries 1 packages: theme-a.
  Within directory hierarchy 'node_modules > theme-a', 'theme-a' stores 1 child directories: src.
  At level 3, in directory path 'node_modules → theme-a → src', 'src' has been left empty.
  At the main level, 'src' organizes 1 subdirectories that organize the source code.
  In nested path 'src / theme-a', Inside 'theme-a', you'll find it stands empty.
  Back to the top level.
