The details
Profile banner at 1500×500 (3:1), JPG or PNG under 1MB. The crop shifts between desktop and mobile and your circular avatar sits over the bottom-left corner, so the safe zone is the middle of the frame.
Safe area: Desktop crops a little off the top and bottom, mobile shaves the sides, and the avatar overlaps the lower-left — keep key elements centered.
