"""A row that is gone answers with a reason the bilingual UI can translate (deep-review round 3).

The 404 a user actually meets is the one for something deleted in another tab or on another device.
`owned_or_404` / `get_or_404` sent it as a bare English string ("Unknown view", "Not found"), and the
Hungarian UI toasted it verbatim. The structured-404 fix had gone into one ad-hoc helper instead of
the shared one, so every other owner check kept the English. Needs the DB.
