//! Embedded JSON Schema (Draft 2020-12) meta-schema of the Graphersal schema format.

/// [`SCHEMA_FORMAT_URL`](crate::graph::schema::SCHEMA_FORMAT_URL) (the file
/// `graphersal-schema-v1.json`). Editors can use it for completion; the engine's own loader
/// is stricter (it also checks the keyword applicability, `$ref` targets and patterns).
