// W21 (rehearsal 2026-10-20): „switch on" with no household SMB password answered „Beállítás mentve. A megosztási
// szolgáltatás előkészítése folyamatban…" — but reconcile never deploys without the password („deploy skipped —
// household SMB password not set yet") and the page stayed „Állapot: áll" for ever. The answer and the page now ask
// for the password at once and say why the service waits; with a password set, the bring-up is unchanged.
