### Negative Consequences

* **Historical inconsistencies**: Existing code may contain British English spellings that cannot be changed due to backward compatibility

### Migration and Enforcement

* **New code**: All new contributions must use American English

- Use clear, concise technical Traditional Chinese consistent with existing docs.
- Address the reader naturally (commonly using “你/你的”).

### Headings

- Follow existing Traditional Chinese heading style (short and descriptive).
- Do not add trailing punctuation to headings.

### Quotes and punctuation
