 *  * When an entry is being **edited**, it is not necessary to supply data for every value; values

1) Prefer Japanese corner brackets 「」 in normal prose when quoting a term.
2) Do not change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

1) Keep ellipsis style consistent with existing Japanese docs (commonly `...`).
2) Never change `...` in code, URLs, or CLI examples.

### Preferred translations / glossary

Use the following preferred translations when they apply in documentation prose:
