React-TS Rules

• Use TypeScript 4.9+ strict mode.
• Follow React 18 functional components + hooks only.
• Use Redux-Toolkit for state, React-Router v6 for routing.
• CSS Modules + PostCSS (preset-env, autoprefixer). No Tailwind.
• Run yarn lint (tsc + eslint + stylelint) before every commit.
• Prefer named exports; barrel-indexes via index.ts.
• No console.log in production code (no-console: 2).
