// GDEY075T7 - 7.5" 800x480 mono, UC8179 (GD7965). Captured clean from the
// stock GxEPD2_750_GDEY075T7 driver (single region, 1bpp, no hand-assembly).
// Same controller family as GDEQ0583T31 (panel_583_gdeq0583t31.h), and it
// shows: identical 0x90 window bracketed by 0x91 "partial in" / 0x92
// "partial out", 0x13 plane write, and a full _InitDisplay() re-run before
// the 0x12 refresh trigger on every cycle (the UC8179 "double-init" quirk) -
// so 0x91+0x90 sit in window_sequence and 0x92 + the re-init + 0x12 make up
// refresh_sequence, exactly as on the 583.
