  Network/version lifecycle for Acala EVM+. Acala runs a production mainnet
  (Acala, chain id 787) plus a beta/staging channel, its Kusama sister network
  Karura (686), and the Mandala TC9 testnet (595) for development. Versioning is
  by network + runtime upgrade (Substrate on-chain runtime versioning) rather
  than a dated REST API version.
