Ganma 猫验证码界面

Create a realistic CAPTCHA verification interface image. The top section is a solid blue header bar containing white text: 'Select all squares with' in small font, followed by 'ganma_cat' in large bold lowercase font, and 'If there are none, click skip' in smaller text below. Beneath the header is a 4x4 grid of square tiles separated by thin white lines. The grid displays a single continuous photo of a white cat with large yellow-green eyes and pink ears, wearing a black hoodie. The background behind the cat is a plain beige wall.
