1) Convert neutral double quotes (`"`) to German double typographic quotes (`„` and `“`). Convert neutral single quotes (`'`) to German single typographic quotes (`‚` and `‘`).

Do NOT convert quotes in code snippets and code blocks to their German typographic equivalents.

Examples:

Source (English):

```
"Hello world"
“Hello Universe”
"He said: 'Hello'"
“my name is ‘Nils’”
`"__main__"`
`"items"`
```

	err = syscall.Statfs(path, &s)
	if err != nil {

	info = Info{
		Total:  uint64(s.Frsize) * (s.Blocks - reservedBlocks),
		Free:   uint64(s.Frsize) * s.Bavail,
		Files:  s.Files,
		Ffree:  s.Ffree,
		FSType: getFSType(s.Type),
	}

### Quotes and punctuation

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

### Ellipsis

- Keep ellipsis style consistent within each document, prefer `...` over  `……`.
- Never change ellipsis in code, URLs, or CLI examples.

### Preferred translations / glossary
