React Render Types — Composition Patterns

Patterns for building React components with @renders type annotations. Covers design system primitives, app-level composition, and advanced techniques.

Annotation Syntax Quick Reference

@renders {X}           Required — must return X
@renders? {X}          Optional — may return X or null
@renders* {X}          Many — zero or more X
@renders! {X}          Unchecked — declares X, skips return validation
@renders {A | B}       Union — must return A or B
@renders {MyAlias}     Type alias — resolves type MyAlias = A | B at lint time
@transparent           Wrapper — plugin looks through to validate children
                       (or use additionalTransparentComponents setting for built-ins)
