// Port of go1.25.5 src/net/http/request_test.go — request-level subset.

// Elided: multipart form tests (TestMultipart*, TestFormFile*, TestParseMultipartForm*) —
// multipart handling is not yet ported. Transport-level tests that boot
// real servers (TestRequestRedirect, TestRequestWriteBufferedWriter).
// TestReadRequestErrors — parses raw HTTP bytes via ReadRequest, which is
// not exposed in goish (server-side only, driven by hyper).
