Notification deep-link scroll targets #comment-{id}. Add the id to
the article wrapper along with tabindex="-1" so scrollIntoView +
.focus({preventScroll:true}) can land screen-reader and keyboard
focus on the specific comment. A focus-visible ring appears only
for keyboard users so mouse clicks don't trigger a visible outline.
