//! Tests for precision coexistence.
//!
//! These tests verify that in `both` mode, `Score32`/`Score64` and their
//! associated types coexist without name conflicts, produce values of the
//! correct types, and remain type-safe (no accidental mixing).
//!
//! This module compiles only when `--features both` is passed.
