Consistent term capitalization

Follow consistent capitalization rules for technical terms, acronyms, and library names throughout your codebase and documentation:

1. Capitalize standard acronyms: Use ‘URL’, ‘JSON’, ‘API’, ‘HTML’, ‘CSS’, ‘Unicode’, etc. rather than lowercase versions.

2. Capitalize product/library names: Use ‘Pydantic’, ‘Django’, ‘React’, etc. when referring to them as proper nouns in documentation, comments, and string literals.

3. Preserve lowercase in code contexts: Keep technical names lowercase when used in import statements, function calls, or paths where they must match the actual implementation:

   # Correct:
   import pydantic  # lowercase in import statements
      
   # In documentation or comments:
   # Pydantic provides validation for Python data types  # capitalized as proper noun
   

This consistency enhances readability, maintains technical accuracy, and provides a more professional appearance in your documentation and user-facing messages.
