Below is a unified diff and a review comment. Identify the minimal contiguous code range in the diff that the comment targets.

Rules:
1. Copy the relevant lines VERBATIM from the diff — do not rewrite, reformat, or add anything.
2. Strip leading diff markers (`+`, `-`, ` `) from each line before outputting.
3. Include only the lines directly related to the issue — no surrounding context.
4. If multiple disjoint locations apply, pick the single most relevant one.
5. Output ONLY a fenced code block. No explanation, no commentary.

**Diff:**
```diff
{diff}```

**Original code snippet (failed to match):**
```
{existing_code}
```

**Review comment:**
{suggestion_content}
