Heuristic UI layout & usability review of the kitsoki web UI. Walks the onboarding tour manifest at mobile/tablet/desktop, runs a deterministic DOM-geometry + axe-core audit per step, then fans the frames out across MULTIPLE read-only claude vision agents (one per surface, so no single agent holds every image) that critique each surface against a Nielsen-based heuristic catalog, adversarially re-checked, and emits a gated review-report.md + verdict.json with concrete fixes. Use when asked to review / critique / find layout, usability, responsive, or accessibility problems in the kitsoki web UI — distinct from kitsoki-ui-qa (which checks "does the demo SHOW scenario X").
