• 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.
• Use lowercase with dashes for directories (e.g., components/auth-wizard).
• Favor named exports for components.
• Use TypeScript for all code; prefer interfaces over types.
• Avoid enums; use const objects or as const assertions instead.
• Use functional components with TypeScript interfaces.
• Use arrow functions for components and handlers.
• Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements.
• Use declarative JSX.
