Composition patterns for building flexible, maintainable React components. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. These patterns make codebases easier for both humans and AI agents to work with as they scale.

isCompact, isDisabled, showHeader のようなboolean propが増殖すると組み合わせ爆発を起こす。代わりにcomposition(children, compound components)で構造的に解決するrenderHeader, renderFooter のようなrender propsはchildrenやcompound componentsで代替できるケースが多い。childrenを優先し、render propsは最後の手段とする
