  Seismic ships a fork of Foundry ("sfoundry") as its primary developer CLI
  toolchain for writing, testing, and deploying shielded smart contracts. The
  binaries are installed via the sfoundryup installer. Captured verbatim from
  the Seismic installation and development-toolkit docs.

key_flows:
  - Write and test contract code locally with sforge before deployment.
  - Run a local Seismic node (sanvil) for development and integration testing.
  - Deploy an SRC20 token to the Seismic testnet (see sandbox/seismic-systems-sandbox.yml).
