// Off-site-by-default (operator ruling 2026-09-16) — the same shape as DR-tier-by-default, and for a
// sharper reason: with the box's off-site copy unticked, a one-drive box keeps NO copy of the
// household's own files. The whole-guest tiers do not carry the data drive (07-backup-architecture
// §6) and a Tier-1 unit holds no file leg, so the files are covered by Tier 2 or Tier 3 and by
// nothing else. On 2026-09-16 that was measured, not argued: five photos deleted on a fresh box,
// restored from the box's own backup, and none of them opened.
//
// Red-proof partner: drop the overrides from handleConfigNewForm → this test fails at the checkbox.
