Case Conversion Rules & Grammar Logic
Title Case applies a stop-word dictionary (articles, prepositions, and coordinating conjunctions under 4 letters) keeping them lowercase unless they are the first or last word. camelCase strips non-alphanumeric delimiters and capitalizes every word after the first. snake_case replaces whitespace and hyphens with underscores in lowercase.
