Supported Capitalization Styles
- Sentence case: Capitalizes the initial letter of every sentence while keeping subsequent letters lowercase, following natural prose grammar.
- UPPERCASE: Converts every alphabetical character to capital letters, commonly used for legal disclaimers, warnings, and database constants.
- lowercase: Converts all characters to small letters, ideal for cleaning up raw URL slugs, email addresses, and server filenames.
- Title Case: Capitalizes major content words following standard editorial style guides (such as APA, MLA, and Chicago Manual of Style).
