    Style Case Definitions:

    1. Snake Case:
       - Definition: Words are separated by underscores.
       - Example:
         'example_string_here'

    2. Kebab Case:
       - Definition: Words are separated by dashes.
       - Example:
         'example-string-here'

    3. Camel Case:
       - Definition: The first word is lowercase, and subsequent words have their first letter capitalized with no separators.
       - Example:
         'exampleStringHere'

    4. Pascal Case:
       - Definition: Every word starts with a capital letter with no separators.
       - Example:
