# tokio is ONLY needed by the binary (main.rs) for #[tokio::main].
# lib.rs has no direct tokio dependency — it exposes plain async fns that are
# runtime-agnostic. Downstream library consumers bring their own runtime and
# can freely choose any flavor, e.g.:
#   tokio = { version = "1", features = ["rt-multi-thread", "macros"] }
# and use #[tokio::main] (multi_thread is the default flavor).
# RdapClient is Send + Sync so it works across thread-pool tasks too.
