Review Comment:
   The guard for “single-level pages (just Home > Page)” doesn’t match the 
condition here: `items` always contains `Home`, so a single-level page produces 
`items.length === 2` and will still generate breadcrumbs. Either adjust the 
condition (e.g., treat `items.length <= 2` as single-level) or update/remove 
the comment so the behavior and intent are consistent.
   ```suggestion
     if (items.length <= 2) return null;
   ```
