// R-675: when a unit restore is refused for a file app, the sentence must name the route that brings
// the files back. Since decision 26 (v0.269.0) a second drive holding a WHOLE copy has its own action
// („Teljes visszaállítás a másolatból") — but the refusal still sent the household to the file-only
// „Fájlok visszaállítása". The consequence asserted: for each real state the household reads the right
// button name, in both languages; the whole copy wins over the file-only copy, and off-site still wins.
