Generate an A2 β-casein ingredient information page. The composition uses a soft milky white background, with ample blank space at the top and left sides; In the center, a pale yellow egg white sheet with a fine powdery texture is placed vertically, with the bottom gently supported by pure white milk and a small amount of white, rounded granules floating around it. Three ultra-fine gray-brown guide lines point to the main body, labeling "protein source," "light taste," and "daily nutrition," each accompanied by a short line. On the bottom left, use large black modern Han font to write "A2 β-casein", and on the next line, use the same simple typeface to write "Friendly and Harmonious." Titles and notes use rational, restrained sans-serif fonts, keywords can be light wheat yellow, and the lines remain thin and smooth. Do not include formula cans, brands, infant figures, medical or digestive treatment commitments, original image standard numbers, footnotes, white borders, watermarks, or obvious shadows in screenshots.
