### Quotes and punctuation

1) Keep punctuation style consistent with existing Simplified Chinese docs (they often mix English terms like “FastAPI” with Chinese text).
2) Never change punctuation inside inline code, code blocks, URLs, or file paths.

### Ellipsis

1) Keep ellipsis style consistent within each document, prefer `...` over  `……`.
