Summary

Closes #50. #global-toolbar is appended inside <main> so landmark navigation can reach Clear All and Open URL. Fixed positioning is unchanged. No skip link and no new accessible name on the toolbar.

Also records A15 as closed (PR #64) on the issue map. That number is not on the A13 row.

Changes

toolbar.js mounts on document.querySelector('main') (falls back to body only if main is missing). position: fixed still pins the tools to the viewport, so the visual slot stays top-right.

Test plan

  • npm test — A13 characterization
  • mcq.md in light: toolbar is inside main, 48px from the viewport right, Clear All still works
  • mcq-with-url-content.md: Open URL and Clear All stay in main and on screen
  • Dark: same fixed toolbar
  • Host iframe landmark list (needs-manual-verify)

📝 Walkthrough

Walkthrough

Toolbar.init() now appends the toolbar to the first <main> element when available and falls back to document.body. The A13 characterization test verifies this placement and confirms that no skip link, aria-label, or role markup is added. The Wave 4 plan records A15 as closed through PR #64 and updates the next-step sequence.

Merge Risk: ⚪ Minimal · up to 30980

The toolbar now mounts inside the main landmark while retaining fixed positioning and its documented fallback behavior. No concrete production defect or merge-blocking risk is identified; the PR is merge-ready after normal checks, with a localized follow-up to improve the placement test.

The implementation satisfies issue #50: it mounts the toolbar inside <main>, falls back to <body>, preserves fixed positioning, adds no skip link or new accessible name, and adds the A13 characterization test.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Test the DOM contract instead of matching source text.

This test never runs Toolbar.init() in a DOM. It does not prove that the toolbar is a child of the first <main>. Line 93 also rejects document.body.appendChild(toolbar), although the contract requires a body fallback when no <main> exists. Use a minimal document fixture to test both placement paths and inspect the actual toolbar attributes and elements.
