1//! GraphQL endpoints.
2//!
3//! - `POST /graphql` - Execute GraphQL queries and mutations
4//! - `GET /graphiql` - GraphiQL IDE (requires `graphiql` feature, on by default)
5//!
6//! Note: `/playground` is intentionally not included. GraphQL Playground was
7//! deprecated and merged into GraphiQL 2.0, making them redundant.
