"""Unit tier: the SSR rendering layer (content.py + format.py) fed committed backend
fixtures via the hermetic `client` fixture (tests/conftest.py). Asserts the rendering
*contract* pages render and carry the expected structure not exact climate numbers
(those are the backend's responsibility). Ported from the old backend-coupled
test_content.py; refresh the fixtures with scripts/capture-fixtures.sh.
