  Karat's example SDK selects the API host from an ENVIRONMENT variable, giving a
  test environment distinct from production. There are no published test cards or magic
  identifiers (Karat is not a payments API); test isolation is by environment + tenant
  token. Roles and candidacies also expose a `demo` filter flag for demo data.
environments:
- name: production
  url_template: https://{subdomain}.karat.io/api/v1/graphql
  live: true
