//! # Bridge Hub Rococo Runtime
//!
//! This runtime is also used for Bridge Hub Wococo. We dont want to create
//! another exact copy of Bridge Hub Rococo, so we injected some tweaks backed by `RuntimeFlavor`
//! and `pub storage Flavor: RuntimeFlavor`. (For example this is needed for successful asset
//! transfer between Asset Hub Rococo and Asset Hub Wococo, where we need to have correct
//! `xcm_config::UniversalLocation` with correct `GlobalConsensus`.
//!
//! This runtime currently supports bridging between:
//! - Rococo <> Wococo
//! - Rococo <> Westend

#![cfg_attr(not(feature = "std"), no_std)]
// `construct_runtime!` does a lot of recursion and requires us to increase the limit to 256.
#![recursion_limit = "256"]

// Make the WASM binary available.
