// The membrane's did:web document — GET /.well-known/did.json makes did:web:<host> (serverDid) resolvable,
// and advertises #bsky_fg when a feed skeleton is served here (Bare: the gateway's lens extension; see
// test/bare/extensions.test.js). The Node edition serves no extensions. Run via brittle-node.
