// ── R-550 — an interrupted restore is SHOWN on the restore page ─────────────────────────────────
//
// Chaos night round 10: a restore interrupted by a hard reset left the page blank. The record now
// survives (internal/backup/restore_record.go); these drive the REAL page through ServeHTTP, so they
// bite on the wiring — a record that exists but that no page renders is the inert-seam shape.

// RED-PROOF: drop `data["InterruptedRestores"]` from backupsRestoreHandler → the card never renders →
// "the restore page does not show the interrupted restore".
