Defect: /site/docs returns a GitHub Pages 404

[eviltester]

Summary

The deployed docs root URL https://eviltester.github.io/grid-table-editor/site/docs returns a GitHub Pages 404 page instead of a docs landing page or redirect. Canonical docs pages such as /site/docs/intro and /site/docs/test-data/... load correctly.

Environment

• Deployed docs root: https://eviltester.github.io/grid-table-editor/site/docs
• Story/PR: turn the method picker into a real MethodPickerDialog MVC #230 / [codex] Implement method picker MVC #247
• Date tested: 2026-06-27

Repeat Steps

1. Open https://eviltester.github.io/grid-table-editor/site/docs.
2. Observe the loaded page.
3. Repeat in a fresh browser context.
4. Compare with https://eviltester.github.io/grid-table-editor/site/docs/intro.

Expected

The docs root should show a documentation landing page, redirect to the docs introduction, or otherwise provide a useful docs navigation entry point.

Actual

The docs root loads a GitHub Pages 404 page with "File not found". The docs themselves are deployed under more specific routes, so this is a root-route/index handling gap rather than a total docs deployment failure.

for consistency, since /blog has an index /docs should probably have one too
