// R-252 / R-253 — A REFUSAL ON THE RECOVERY PATH NAMES A REASON A PERSON CAN ACT ON, AND THE WAY TO
// ACT ON IT.
//
// Both of these were met on the fifth walk (2026-08-07) at the LAST step of a successful recovery —
// the customer had entered their recovery code, seen their data listed, and pressed through. Neither
// needed a shell to clear, which is why the walk's journey half passed; both required knowing
// something the product never said, which is why they are filed.
//
// These assert the RENDERED page, not the state that feeds it: the defect in both cases was copy
// that disagreed with behaviour, and only the rendered bytes can show that.

// restoreData is the healthy fixture — app in the store, installed here, drives registered. Every
// test below overlays exactly one field, so what it proves is attributable.
