"Design a minimalistic infographic that presents the CASE framework for personalized learning. Use four simple, geometric shapes (circles, squares, or hexagons) to represent each step: Content, Abilities, Standards, and Evaluation. Use a neutral color palette with soft pastel colors for each shape. Place each shape in a horizontal sequence, with a thin, elegant arrow pointing upwards at the end to symbolize progress. The background should be almost white, and the text should be minimal, with clean, sans-serif fonts. Icons should be line-based and simple." --s 750
