//! Runtime variable coercion tests: the spec's "Coercing Variable Values" (September 2025,
//! §6.1.2) and the input coercion rules of §3.
//!
//! The tests describe the target behavior, so some of them fail until the router's coercion is
//! fixed. Expected error messages use the graphql-js v17 wording (commit ee5ce41).
