An empty-state panel rendered as an idle e-ink display: a coarse grid of cells continuously replays real electrophoretic drive waveforms on a scattered, ever-changing subset of itself, each replay briefly shooting through to full black or full white before settling, while the whole panel periodically runs a synchronized full-refresh flash to clear ghosting.
