# {{PROJECT_NAME}} — Copilot Instructions

## Architecture
Read DECISIONS.md before making architectural choices. Document new decisions there.

## Code Style
- Constructor Pattern: 1 file = 1 class = 1 responsibility
- File <200 lines, function <30 lines
- Types/interfaces BEFORE implementation
- Tests WITH code, never "later"

## Forbidden
- Mixins, abstract factories, DI containers
- Rewriting working code without reason
- Committing .env, credentials, API keys
- Adding abstractions for one-time operations
