//! Tokenizer test across a mixed domain: ASCII, Cyrillic, Unicode
//! punctuation, JSON, tool-call-like payloads, filesystem paths + CLI flags.
//!
//! Asserts tokenize produces tokens and detokenize round-trips the meaningful
//! content (exact byte-identity is not guaranteed for all normalizers, so we
//! check non-emptiness + substring survival).
