gleam_httpc 4.1.1 still calls result.then, which was removed from
gleam_stdlib 0.71.0. Bumping the lower bound forces the resolver to
pick 4.2.x or later, which uses result.try. The < 5.0.0 cap is also
widened to < 6.0.0; the public API is unchanged between 4.2 and 5.0.
Long term: committing a manifest.toml lockfile would stop transitive
deps from drifting on every fresh build.
A small Gleam HTTP server in signup/ exposes POST /signup that validates
a shared INVITE_CODE env var, then PUTs a user document to CouchDB's
_users database using the existing admin credentials. The frontend gets
back 201 + the username and is expected to call /_session itself to
obtain the AuthSession cookie (chosen over server-side cookie forwarding
because vaquant.at and couch.apoena.dev are different sites and the
cross-site cookie path is fragile under modern browser privacy modes).
Wired into docker-compose as a second service, reachable on
signup-couch.apoena.dev with its own Traefik labels and the same
hardcoded UUID network attachment as couchdb. Reuses COUCHDB_USER /
COUCHDB_PASSWORD for the admin call. INVITE_CODE must be set in Coolify
env vars.
