model: test-mode keys against the live API, plus a hosted try-it explorer
test_keys:
  live_prefix: api_live_
  test_prefix: api_test_
  behavior: >-
    Test keys hit the live API and return the real response structure with no quota or balance
    consumed. Only body and body_html are truncated, suffixed with
    "...[Test mode — use a live key for full content]" — title, description, entities, sentiment,
    categories and source come through in full, including on SSE/WebSocket streams.
  mode_header: 'X-Apitube-Mode: live | test'
  limits:
  - /v1/news/count caps its answer at 100 in test mode — never treat a test-key count as a real volume.
  - /v1/news/trends keeps shape and numbers but masks each entry's value with "[Upgrade subscription plan]".
  - Test keys are rate-limited more strictly than live keys (separate bucket).
  management: Dashboard — Test mode toggle at the bottom of the sidebar, then create keys under API Keys; live and test keys are listed separately per mode.
