About only lived under Settings -> About, which nobody signed out would think to open. The sidebar now carries an About entry pointing at the same page (/settings/about), shown only while signed out; signed in it stays in the settings menu with the rest of the account chrome. Drops the orphaned marketing About screen that the top-level /about path rendered — nothing linked to it, and /settings/about is the About page now. The sidebar also stops lighting up a prefix-matching entry (Settings spans /settings/*) when a sibling entry matches the current path exactly, so only About highlights on /settings/about. Web e2e covers both states (flows/about-link.spec.ts).
