serve.server_accounts lends region-tagged server credentials to remote sessions (round-robin per region, per-key opt-in, per-account cache). Remote sessions no longer fall back to the server's local credentials when the client sends none.
Remote mode resolved names with the local alias table and built an empty stub for any unknown tag, so an unentitled service showed a blank help page. Resolve against the server's tags and aliases, and reject unknown names with the list the server does offer.
The server no longer spends its configured proxy providers on a remote client unless the API key sets server_proxy. It places the client by geolocating the connection address and asks for a proxy when that region does not match its own.
serve.users.<key>.server_cdm accepts a list of service tags; retry re-attaches the job service and a bare string no longer fails open. An unset client server_cdm now follows the server's per-service /tracks flag.
Add serve.services_refresh_interval; refresh pulls the repos and re-imports only the changed services, staging any with active jobs until they finish. Report skipped/broken services in the log and on /api/services.
Render all click help through rich-click, themed by a new `theme` config key (9 palettes + aliases, previewable via `unshackle env theme`), and show service docstrings in local and remote `dl <TAG> -h`.
api-only/remote-only serve now authenticates every serve.users key (str-coerced), not just api_secret, so per-user service allowlists apply. RemoteClient tries X-Secret-Key then X-Api-Key on 401 (sticky winner); remote_services.auth_headers prepends extra header names to the defaults.
