Smoke test

Loads every topic from SUBJECTS in a hidden iframe, watches for console errors, and verifies the SVG mounts with at least one path-or-image and 3 answer options. Run at the end of a session to catch regressions before they land. Click any cell to re-test just that topic.

No failures yet.

What "pass" means: page loaded, no error-level console messages, no un-anchorable-part warning, #svg-container contains an SVG with at least one path or image, and 3 .qv2-option buttons rendered. Timeout: 12 seconds per topic.
What it doesn't catch: visual regressions, anchor-placement drift, content correctness. Pair with /ultrareview for structural review.
