Root cause: Panel_ED2208's epd_quality mode applies _dither_row_rgb_pair (diagonal bias pattern with dither=140) during _exec_transfer(). Since our ImagePipeline already does proper Floyd-Steinberg dithering, the driver's additional dithering was creating visible diagonal artifacts. Fix: setEpdMode(epd_fastest) selects _dither_row_none (clean nearest-color lookup, no spatial bias). On Panel_ED2208 this only affects the dither function — NOT refresh quality or waveform. Also: default dither_noise setting to OFF since error scatter was targeting the wrong layer (it made gradient areas fuzzier without fixing the real problem in the display driver).
