//! Shared marker (ZST) types used for type-level units and coordinate spaces.
//!
//! These are intentionally defined **once** so that all modules agree on the same
//! `Meters/Pixels/World/Local/Screen` types. Re-export them from modules (e.g. `vec2`)
//! if you want `gemath::vec2::Meters`-style paths to keep working.
