Progress

• Reproduced on /blocks/toc-demo.

• Increased nav flash duration to 10s and added visible heading highlight styling, but the standalone route still does not navigate.

• Registry rebuild did not fix the standalone route.

• Confirmed port 3002 serves /Users/zbeyens/git/plate-2/apps/www, not this checkout.

• Next step: sanity check current repo on port 3001 and report the mismatch clearly.

• Verified pnpm --filter www typecheck passed.

• Verified pnpm lint:fix passed.

• Browser proof on http://localhost:3001/blocks/toc-demo: clicking Benefits of Using TOC produced one aria-current="location" row and one data-nav-target="true" heading highlight.
