okay that's the whole page, mwah 🍓 so the tiny fine print at the bottom: this one lives at ./drivers/gpu/drm/amd/display/... and the date on it is October 2026 — mark your calendars, set a reminder, whatever you gotta do 💜 and yeah it's stamped dm_test_app...ay_zero_wait(9) down there too, matching the title, consistent queen 🌈 periodt ✨🧚‍♀️
