Treat type definitions with respect
summary
Argues that TypeScript type definitions deserve the same clean‑code rules as implementation code and gives seven concrete rules: use accurate naming, drop unused attributes, and keep interfaces close to implementation; shows React examples (hooks and components), points out an IntersectionObserver prop that should accept a simple pixel margin instead of exposing complex browser options, recommends placing types next to domain functions instead of a giant types.ts, and advises abstracting third‑party return shapes (AWS) and explicitly typing exported public APIs.
