// R-365 follow-up: at 0 days left the reminder bar's `{{if .RecoveryAbandonDays}}` is false, so a
// countdown whose due moment had PASSED fell back to the undecided-box reminder text — the deletion
// vanished from the bar on the very day it is due — and offered „Ne emlékeztessen újra" over it. The
// consequence asserted through the real data path (addRecoveryBanner, reading a real countdown from
// settings) and the real layout: the bar says the deletion is due since the date, and offers no
// reminder opt-out; a running countdown (negative control) still says „N nap múlva".
