//! Benchmarks for IANA bootstrap server discovery.
//!
//! # What is measured
//!
//! * TLD → RDAP server lookup from a warm (populated) in-memory bootstrap cache.
//! * IP prefix matching (IPv4 and IPv6).
//! * ASN range matching.
//! * Custom server override (hash map lookup).
//! * Cold bootstrap fetch (fetches mock IANA files over local HTTP).
//!
//! # Performance targets
//!
//! | Operation           | Target  |
//! |---------------------|---------|
//! | Warm TLD lookup     | < 1 µs  |
//! | Warm IP lookup      | < 5 µs  |
//! | Warm ASN lookup     | < 1 µs  |
//! | Custom override     | < 500 ns|
//! | Cold bootstrap fetch| < 5 ms  |
