//
// One-time capture: writes Lucid-format protocol parameters from the live
// Vector testnet Ogmios endpoint into protocol-params.fixture.json, using
// OgmiosProvider's own mapping so the fixture can never drift from the
// conversion logic. Run manually after `npm run build`:
//
//   node packages/builder/test/fixtures/capture-protocol-params.mjs
//
// Never runs in CI — unit tests read the checked-in JSON.
