behavior: temporal-visual-verification
prompt: |
  Verify the initial skeleton loading state and the menu open/close interaction in site/loading.html. Actually run the local page in a browser, save the evidence under artifacts/, and capture the sequence rather than only describing a plan.
fixture: visual-site
setup: mkdir -p artifacts
checks:
  - shell: test "$(find artifacts -type f -name '*.webm' -size +1k | wc -l | tr -d ' ')" -ge 1 && find artifacts -type f -name '*.webm' -exec file {} \; | grep -q WebM
  - judge: The report identifies the saved video evidence, describes the initial skeleton, loaded state, menu-open state, and menu-closed state, gives the observed result, and does not falsely claim artifact delivery.
