//! # TINNITUS — Persistent Ultrasonic Micro-Attestation Sub-Channel
//!
//! This crate is a **top-level name claim** for TINNITUS™, the persistent
//! ultrasonic sub-channel of [`gibber-link`](https://crates.io/crates/gibber-link)
//! within the BCCCOP™ protocol family. It intentionally contains no functional code.
//!
//! TINNITUS operates at 15,000–22,000 Hz — above most adult hearing, below
//! microphone hardware limits — carrying always-on micro-attestation tokens and
//! presence beacons. The name is a deliberate metaphor for medical tinnitus:
//! a constant, imperceptible tone, always present, always carrying signal.
