Manual items (not covered by automated audit)

• M1 — Screen-reader walkthrough (pending): VoiceOver (macOS) walkthrough of each step in all 5 assessments using QA bypass (?qa=nxf-qa-8f2k) to unlock all steps. Test: heading order within each step, ARIA live-region announcements on MCQ submit, focus management when a step unlocks, RubricPanel toggle announce. Target: zero critical/serious issues. Owner: LD team or QA engineer.
• M2 — LXD tool (public/index.html) audit (pending): The LXD tool is a standalone static SPA not included in this automated Lighthouse run (it requires a separate static server). Run axe-core or Lighthouse against it separately. Owner: LD team.
• M3 — Keyboard-only navigation test (pending): Tab through each assessment step without a mouse. All interactive elements (MCQ options, rubric toggle, submit, back) must be reachable and operable by keyboard alone. Owner: LD team or QA engineer.
