### `///` admonitions

1) Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
2) Many Traditional Chinese docs currently omit titles in `///` blocks; that is OK.
3) If a generic title is present, prefer these canonical titles:

- `/// note | 注意`

Notes:

- `details` blocks exist; keep `/// details` as-is and translate only the title after `|`.
- Example canonical titles used in existing docs:
