assert POST requests whose Content-Type has a non-JSON media type containing application/json in parameters reject with HTTP 415 and error code -32000 rather than passing the gate
assert case-insensitive media types such as Application/JSON and parameters like charset=utf-8 pass the Content-Type gate with HTTP 200
assert malformed parameter sections with an unambiguous media type like application/json; fall back to the segment before the semicolon and pass the gate
assert joined duplicate Content-Type headers reject with HTTP 415
assert missing and non-JSON Content-Type headers reject with HTTP 415
assert client StreamableHTTPClientTransport rejects responses with non-JSON media types containing application/json parameters with StreamableHTTPError rather than parsing them
assert client StreamableHTTPClientTransport rejects responses with non-SSE media types containing text/event-stream parameters with StreamableHTTPError rather than parsing them
assert client StreamableHTTPClientTransport accepts case-variant Application/JSON responses and dispatches the JSON-RPC message to onmessage
assert mediaTypeEssence extracts the lowercased MIME essence and returns undefined for joined duplicate headers with parameters
assert isJsonContentType rejects non-JSON essence and accepts valid or parameter-bearing application/json variants
