"""custom-html — RESTORE overlay (Phase 1d, DG4): data-integrity, extends the generic restore.

Runs after the backup overlay (test_backup.py) on the SAME shared deployment, which left state
mutated to "mutated" after backing up "original". This restores the snapshot via the shared op
helper (`generic.do_restore`, which also asserts the app is healthy + serving afterwards), then
asserts the served data returned to the pre-mutation "original" — the app-specific data integrity the
generic restore cannot check. Assertion-only (no deploy/teardown)."""
