  First-party Seismic client libraries for building on the Seismic encrypted
  blockchain (shielded transactions, encrypted calldata, signed reads). Verified
  against the public package registries at fetch time: seismic-viem and
  seismic-react resolve on the npm registry (2.0.1); seismic-web3 resolves on
  PyPI (0.2.2). seismic-alloy is the Rust SDK, distributed from the SeismicSystems
  GitHub org and consumed via Cargo. @seismic/src20-sdk is an internal workspace
  package and is intentionally NOT published to npm, so it is excluded here.
