// Credentials are read from `pass` so they never appear in argv or env. The
// API token, email, and domain are loaded from the canonical entries:

//	pass jira/anjana/api-token

// rewritten (encrypted at rest by saveModule). The kanban module key
// (KANBAN_MODULE_KEY env var) must be set — the same value the running server
// uses, otherwise the server cannot decrypt the secrets we wrote.
