Fixed

On X3, Quick Resume now performs a second no-flash reinforcement pass before powering down the display. The first pass adds the sleep indicator; the second repeats the unchanged black-and-white settle waveform so retained white and black pixels are more firmly stabilized for long standby periods.

This addresses the occasional case where a retained reading page could gradually darken and white areas could drift toward gray while the reader was asleep. Quick Resume still avoids a full-screen black flash. X4 behavior is unchanged.

No settings reset is required.
