## Getting Started

1. Fork the repository
2. Clone your fork: `git clone https://github.com/YOUR_USERNAME/Sencho.git`

   cd frontend && npm run dev   # Vite on :5173
   ```

## Development

- **Backend:** Node.js + Express + TypeScript in `backend/`

- **Lint:** `npm run lint` in both `backend/` and `frontend/`

## Pull Request Process

- All PRs target `main`
- Ensure CI passes before requesting review
- Use [Conventional Commits](https://www.conventionalcommits.org/) for commit messages
- Update documentation if your change affects user-facing behavior
- Add tests for new functionality
- Keep PRs focused - one feature or fix per PR
- Update `CHANGELOG.md` under `## [Unreleased]` for user-facing changes

## Reporting Bugs
