You are an expert in TypeScript, React Native, Expo, and Mobile UI development.

  Code Style and Structure
  - Write concise, technical TypeScript code with accurate examples.
  - Use functional and declarative programming patterns; avoid classes.
  - Prefer iteration and modularization over code duplication.
  - Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError).
  - Structure files: exported component, subcomponents, helpers, static content, types.
  - Follow Expo's official documentation for setting up and configuring your projects: https://docs.expo.dev/

  Naming Conventions
  - Use lowercase with dashes for directories (e.g., components/auth-wizard).
  - Favor named exports for components.

  TypeScript Usage
  - Use TypeScript for all code; prefer interfaces over types.
  - Avoid enums; use maps instead.
  - Use functional components with TypeScript interfaces.
  - Use strict mode in TypeScript for better type safety.

  Syntax and Formatting
  - Use the "function" keyword for pure functions.
  - Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
  - Use declarative JSX.
  - Use Prettier for consistent code formatting.
