## Types

- Avoid explicit type annotations when TypeScript can infer.
- Do not use `any`, casts, or explicit generic type arguments when inference is sufficient.

## Variables

- Use consistent, descriptive naming; avoid obscure abbreviations.
- Prefer direct property access when destructuring only shortens access, even when a property is used multiple times. Destructure only when it significantly improves readability.

## Asynchronous

- Prefer `async`/`await` over callbacks or `.then()` chains
