   When a fetch request spans multiple partitions with a mix of local and 
remote (tiered storage) data, the broker can return more than `fetch.max.bytes` 
in a single response. For example, with `fetch.max.bytes=1MB`:
   
   - If partition 1 returns 1 MB from local storage
   - And partition 2 returns 1 MB from tiered storage
   - The total response can be 2 MB, exceeding the configured limit
   
   This can cause consumer-side issues if consumers aren't configured to accept 
payloads this large.
