//! Fuzz scope parsing (`protocol::scope::ScopeSet`, RFC 6749 §3.3).
//!
//! The raw `scope` value is hostile input: tokens split on single `0x20`
//! spaces with no empty tokens, length- and count-capped. Parsing must never
//! panic; an accepted set re-renders to the canonical wire form
//! (single-space-joined, sorted, deduped), which parses back to the same set.
