Defect: App page lacks main landmark and H1

[eviltester]

Summary

The deployed app page at https://eviltester.github.io/grid-table-editor/site/app.html has no main landmark and no H1, making orientation harder for keyboard and assistive-technology users.

Steps

1. Open https://eviltester.github.io/grid-table-editor/site/app.html.
2. Inspect the DOM or accessibility structure.
3. Check for main, [role=main], and h1.

Observed

Repeated probes at desktop and mobile viewports found:

ext main landmarks: 0 h1 elements: 0

Expected

The app page should expose a main landmark and page-level heading for the primary editor surface.
