Chữ ẩn ảo ảnh thị giác tạo từ đàn chó nông trại

A realistic photo of a group of dogs scattered across a farm field, naturally positioned so their bodies, postures, and shadows form the hidden optical illusion word "[Toolfolio]". The typography should be extremely subtle and blend seamlessly into the environment, invisible at first glance and only legible when squinting or viewing from a distance. Natural daylight, pastoral farm setting, believable canine behavior.
