  Crimson Education publishes no sandbox programme, no test credentials, no magic
  test identifiers and no self-service signup. What it does publish is a named
  staging environment in the SDK README, which is recorded here. No test values have
  been invented — this artifact records an environment separation, not a usable
  public sandbox.

separation_model:
  mechanism: separate host per environment
  key_prefixes: none published
  mode_flag: none — the environment is selected by the apiUrl passed to the SDK client
  notes: >-
    Unlike providers that separate test and live by key prefix or a mode flag, Crimson
    separates by base URL only. The same three auth modes apply to both hosts.
local_development:
  standalone_auth_helper: persistStandaloneAuth(payload)
  description: >-
    The SDK ships persistStandaloneAuth for non-iframe local debugging — it writes the
    auth payload to localStorage and fires the ready event so an embedded app can be
    run outside its parent frame. This is a developer convenience for local work, not
    a hosted sandbox.
