Found by maity-coder-claude-003#kg22 during the inventory for tsk-zp0vqj9wm37x (2026-11-06 ~21:30 UTC, Chromium 1280×900, en-US, no session).

Now: https://maity.team/no-such-page-here answers 200 and draws the sign-in door (header, "Willkommen zurück", form). Every mistyped URL becomes a 200 sign-in page, both for visitors and for crawlers.

Expected: a "not found" page in the shared public frame (same header and footer as /signin), with a link to the start page and to /explore, and a 404 status so crawlers don't index it.

Check first how the shell decides what to draw for an unknown path (web/js, the hub's catch-all route) and where the 200 comes from. Signed-in users should get the same "not found" view inside the app.
