Weekly case conversion: keep style rules and exceptions

For a repeated Case Converter task, record the target style and exceptions for brands, acronyms, code identifiers, and locale-sensitive names. Test a small sample before processing the week's full text. Compare output with source for characters that may change under Unicode case rules. Do not let a formatting routine rewrite IDs or URLs that rely on exact bytes. A stable style guide is more valuable than repeatedly choosing a converter option from memory.
