# PRODUCTION - The Idle Game

> **"Build the Ultimate Global Supply Chain Empire."**

**Production - The Idle Game** is an expansive, strategic incremental/idle tycoon simulator inspired by *Factorio*, *Capitalism*, and modern industrial engineering games. Take command of a burgeoning enterprise, starting from primary extraction (wheat, timber, iron ore) and scaling into complex, multi-tiered industrial supply chains producing microchips, commercial trucks, consumer smartphones, electric hypercars, quantum computers, and space launch vehicles.

The game is packaged as a lightweight, turnkey **Docker Compose stack** powered by a fast Python FastAPI backend with SQLite persistence and a high-performance Nginx reverse-proxy frontend.

## 🚀 Quick Start with Docker Compose

### 1. Prerequisites
* [Docker](https://docs.docker.com/get-docker/) & [Docker Compose](https://docs.docker.com/compose/)
* (Optional for standalone testing) Python 3.10+

### 2. Configuration (.env)
Create a `.env` file from the example:
```bash
cp .env.example .env
```

### 3. Launch the Stack
```bash
docker compose up -d --build
```

The game is live in your browser at:  
👉 **`http://localhost:8081`** (or the port defined in `.env`).

### 4. Running Verification & DAG Validation
To run the automated backend engine simulation tests:
```bash
python backend/test_engine.py
```

To run the automated supply chain integrity and DAG validator:
```bash
python backend/validate_dag.py
```
*(Verifies cycle-free graphs, valid input/output dependencies, positive tier-margin economics, and file reference consistency across all modular sectors.)*

## 🎨 Asset Generation & Custom Visuals

* Refer to [`FACILITY_PHOTO_PROMPT_GUIDE.md`](./FACILITY_PHOTO_PROMPT_GUIDE.md) for master prompts and camera recipes to generate photorealistic assets for production facilities and commodities using modern image models (Midjourney, Stable Diffusion, Imagen). Dropping generated images into `frontend/assets/images/facilities/` and `frontend/assets/images/products/` seamlessly populates the cards and dossiers.
* Refer to [`PRODUCT_GENERATOR_GUIDE.md`](./PRODUCT_GENERATOR_GUIDE.md) when generating new products, supply chain DAG tiers, or entire industry sectors.
