Scaffold NewApproach: Full-stack Bun+Hono+TypeScript+TailwindCSS project

- Create modular project structure with src/backend, src/frontend, public
- Hono server with routing, static file serving, and API endpoints
- TailwindCSS styling pipeline with Tailwind CLI
- Vanilla JS frontend (extensible for frameworks)
- Complete TypeScript configuration and type checking
- Auth module as self-contained submodule
- Ready for development: bun run dev (port 3000)
- All dependencies installed and tested

Also:
- Lock main branch with read-only settings in VS Code
- Create .github/copilot-instructions.md with Monica persona
- Initialize session logging system

Status: Project ready for feature development

+# NewApproach
+
+A full-stack TypeScript application with Hono backend, TailwindCSS styling, and Bun runtime.
+
+## Stack
+
+- **Runtime**: Bun (fast JavaScript runtime and package manager)
+- **Backend**: Hono (lightweight web framework)
+- **Language**: TypeScript (both frontend and backend)
+- **Styling**: TailwindCSS + PostCSS
+- **Package Manager**: Bun
+

+```
+
+## Installation
+
+```bash
+bun install
+```
+
+## Development
+
+```bash
+# Start development server with hot reload
+bun run dev
+```
+
+Server runs on `http://localhost:3000`
+
+## Build
+
+```bash
+# Build CSS and TypeScript
+bun run build
+```
+
+## Available Scripts
+
+- `bun run dev` - Start development server with watch mode
+- `bun run build` - Build styles and backend code
+- `bun run build:styles` - Compile TailwindCSS to output.css
+- `bun run start` - Run production build
+- `bun run typecheck` - Check TypeScript types without building
+
+## Architecture Notes
+
+- **Backend**: Hono with simple routing and static file serving
+- **Frontend**: Vanilla JavaScript with TailwindCSS (no framework required, extensible)
+- **Styling**: TailwindCSS utilities only; custom CSS documented when added
+- **Auth**: Modular auth system in `/src/auth` (decoupled from app logic)
+
+## Environment
+
+Configure with environment variables (`.env` file):
+```
+PORT=3000
+```
+
+## Notes
+
+- The auth module is self-contained and can be used independently
+- TypeScript compilation and type checking ensure type safety
+- TailwindCSS purges unused styles in production builds
+- Bun handles all package management and script execution
