Add Playwright configuration and initial tests for landing page

- Created playwright.config.ts for test configuration - Added .last-run.json to store test run status - Implemented landing.test.ts with tests for navbar visibility and navigation - Removed unused server proxy configuration from vite.config.ts

+# Copilot Instructions for AITrader
+
+## Quick Start
+
+This is a stock trading application built with React Router 7, TypeScript, and TailwindCSS, integrating with the Alpaca trading API.
+
+### Essential Commands
+- `npm install` – Install dependencies (first time only)
+- `npm run dev` – Start development server at `http://localhost:5173`
+- `npm run build` – Create production build in `./build`
+- `npm start` – Serve production build (requires `npm run build` first)
+- `npm run typecheck` – Validate TypeScript (`react-router typegen` + `tsc`) — **must run before committing**
+- `npm run test:e2e` – Run Playwright end-to-end tests
+
+## Architecture Overview
+
+### Project Structure
+```
+app/
+├── root.tsx                 # Root layout and error boundary
+├── routes.ts               # Route configuration (React Router 7 RouteConfig API)

+├── types.ts              # TypeScript interfaces (IndicatorData, AlpacaAccount)
+└── app.css               # Global styles
+```
+
+### Full-Stack Data Flow
+1. **Client (React Components)** – User interacts with `StockViewer` or `AlpacaAccountInfo`
+2. **Server Routes (`/routes/api/`)** – Handle business logic (fetch data from external APIs, run calculations)
+3. **Utils** – Pure functions for indicators and shared logic (testable with Vitest)
+4. **External APIs** – Alpaca API for account/trading data
+
+### Server-Side Rendering (SSR)
+- Enabled by default (`ssr: true` in `react-router.config.ts`)
+- Routes can export loaders for initial data fetching
+- Use `loader` functions in route definitions for data pre-loading
+
+## Key Conventions
+
+### TypeScript & Type Safety
+- **Path alias** – Use `~/` for app imports (e.g., `import { IndicatorData } from "~/types"`)
+- **Generated types** – React Router generates types in `.react-router/types/` after running `typecheck`
+- **Route types** – Import `type { Route }` from `./+types/[routename]` for loader/action types
+- **Never skip `react-router typegen`** – Directly running `tsc` will fail; always run `npm run typecheck`
+- **ES Module syntax** – Project uses `"type": "module"`; include file extensions in imports where needed
+
+### Component Patterns
+- **Client-side interactivity** – Use React hooks (`useState`, `useEffect`) in components
+- **API calls** – Fetch from `/api/*` endpoints; proxy configured in `vite.config.ts` routes to local dev server
+- **Error handling** – Wrap API calls in try/catch; set error state for UI display
+- **Loading states** – Track `loading` boolean to show spinners/disable buttons during async work
+
+### API Route Patterns
+- Handlers in `app/routes/api/**/*.ts` are server-only functions
+- Export a default `export default function(...)` that receives request context
+- Return JSON responses or error responses
+- Use utilities in `~/utils/` for shared logic (e.g., indicator calculations)
+
+### Testing
+- **Unit tests** – Use Vitest (`npm run test:e2e` actually runs Playwright, but unit tests exist via `vitest`)
+  - Located alongside source files in `__tests__/` directories
+  - Test format: `*.test.ts` or `*.test.tsx`
+- **E2E tests** – Playwright configured in `playwright.config.ts`
+  - Tests in `./tests/` directory
+  - Dev server starts automatically during test runs
+  - HTML report generated in `test-results/`
+
+### Styling
+- **TailwindCSS** – Configured via Vite plugin (`@tailwindcss/vite`); no separate build step needed
+- **Global styles** – Edit `app/app.css`
+- **Component styles** – Use Tailwind utility classes directly in JSX
+
+### Import Paths
+- **Absolute imports** – Use `~/` alias for app folder (e.g., `~/components/StockViewer`)
+- **Relative imports** – Use `./` or `../` sparingly within same directory tree
+
+## Common Pitfalls
+
+- **`npm start` fails if build doesn't exist** – Always run `npm run build` first
+- **TypeScript compilation errors after route changes** – Missing `npm run typecheck` step; regenerated types in `.react-router/types/` are required
+- **Vite proxy not working in dev** – Ensure dev server is running and API endpoints match `vite.config.ts` proxy config (default: `/api` → `http://127.0.0.1:3000`)
+- **No test framework exists for unit tests** – Repository includes Vitest/Playwright dependencies but no test runner script; configure as needed
+- **Port conflicts** – Dev server uses `5173`, Docker/production uses `3000`
+
+## Deployment
+
+### Docker
+```bash
+docker build -t aitrader .
+docker run -p 3000:3000 aitrader
+```
+Ensure `npm run build` is run in the Dockerfile before the final `CMD`.
+
+### Environment Variables
+- Check Dockerfile for any required environment setup
+- Alpaca API credentials likely needed for trading features (not present in repo; set at runtime)
+
+## Debugging Tips
+
+- **Type errors** – Run `npm run typecheck` to regenerate React Router types and validate all TS
+- **Module resolution** – Check `tsconfig.json` for path aliases and ensure imports match configured paths
+- **Component not rendering** – Check route configuration in `routes.ts` and ensure component is exported as default
+- **API calls failing** – Verify Vite proxy config and that the target server is running
