Detailed Description

Zero-sized reference-center tag types mirroring Rust's centers module.

Each center is a unique empty struct used as a compile-time tag for position templates. Every tag carries a static ffi_id mapping to the C enum, and optionally a Params type for parameterized centers (Topocentric, Bodycentric).
