Findings

• toc-node.tsx source already uses aria-current={item.id === activeContentId ? 'location' : undefined}.

• Rebuilt registry JSON still reflects that source.

• On /blocks/toc-demo, live DOM/React props show every TOC row has aria-current=true.

• On /blocks/toc-demo, TOC clicks do not change scroll position and do not produce [data-nav-highlight].

• Port 3002 cwd: /Users/zbeyens/git/plate-2/apps/www

• plate-2 toc-node still has bare aria-current on every row and old click-only hook.
