Description

According to the standard, HTTP header names are case-INsensitive.
As it turned out, some environments (by which I mean Kubernetes) may treat this literally and convert response header names to lower case on-the-fly.
Need to check whether we handle this case correctly (spoiler: most likely not).

No files, tests, or entry points are named. Start by locating the backend response-header handling and check its behavior with mixed-case and lower-case header names, then add coverage showing that Kubernetes-style lower-cased headers are handled correctly.
