//! Deterministic DAG-CBOR codec for authoritative, cryptographically
//! signed data.
//!
//! The decoder is strict by construction: it rejects non-canonical
//! integers, indefinite-length items, floats, tags, out-of-order map keys,
//! and trailing bytes, so a given value has exactly one accepted encoding.
//! Decoding untrusted input is bounded in both memory and stack depth —
//! container length prefixes are checked against the remaining input
//! before any allocation, and nesting is capped at
//! [`MAX_NESTING_DEPTH`] — so neither a crafted length nor pathological
//! nesting can drive an out-of-memory or stack-overflow abort.
