// `detector!` is `#[macro_export]` so it's reachable as
// `crate::detector!` — but the `pub use` re-export of a macro
// works at the crate root, not via the prelude `pub use` chain.
// Users get the macro via `use netring::detector;` (always-on
// when feature gates allow). The prelude doesn't need to
// re-export it explicitly — including it in `use netring::prelude::*;`
// implicitly imports the crate-root macro under standard
// 2024-edition macro hygiene rules.
