What the model said
That sanity-check command was blocked (no approval surface in this session), but it was just a read-only check — no changes were affected. The edits to `0.html` are already applied. Summary of improvements made to `0.html`: - Added `<meta name="robots">` for SEO hygiene. - Nav now highlights the section actually in view via `IntersectionObserver` (scrollspy), replacing the static/incorrect `aria-current="page"` on "Home". - Added subtle hover opacity transition on links. - Tightened paragraph max-width for readability and reduced body margin on small screens. You can open `0.html` directly in a browser to see the scrollspy highlighting as you scroll between sections.
