//! HTTP/1.1 obsolete text handling tests.
//!
//! Test suite for verifying correct handling of obs-text in HTTP/1.1 headers.
//! Obsolete text allows characters outside the ASCII range (0x80-0xFF) in
//! header values for backward compatibility with legacy systems.
//!
//! # Standards Compliance
//! - RFC 7230 Section 3.2.6 (Field Value Components)
//! - Latin-1 fallback encoding for non-ASCII bytes
//! - Proper rejection of invalid character sequences
