- Pulse RESET low before User ID read so SSD1680 wakes from deep sleep - Replace ad-hoc LUT with GxEPD2_4G reference (VS L0↔L3 swapped, 0x48 DC balance) - VCOM=0x24 empirically tuned for FPC-7519rev.b contrast - Both 0x44 (FPC-7619rev.b) and 0xca (FPC-7519rev.b) share the same sequence Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Tested on an original MagTag and on a MagTag 2025 0x44. Original is the same, and the 0x44 has much-improved display quality, as seen during testing.
Thanks @mikeysklar!
