Claude风格

The specific style of the PPT should follow the "warm academic humanism" design in the "Anthropic/Claude style".
Background: Use warm beige/cream (#F3F0E9) as the base color to mimic the texture of high-quality paper.
Fonts: Use elegant Serif for headings and modern Sans-serif for body text.
Color scheme: The main colors are terracotta red (#D67052) and mustard yellow (#F0B857), complemented by deep navy blue as an accent. Avoid neon colors or pure black.
Visual elements: Adopt a grid layout that emphasizes typesetting. The illustration style should be abstract, organic black hand-drawn line art placed on solid terracotta red blocks. Some key information should use a card layout.
Charts: Flat, minimalist bar charts that emphasize data comparison and eliminate unnecessary borders.
