# Facility & Commodity Visual Identity — Master AI Prompting Guide

This master prompting guide defines the unified photographic aesthetic, technical camera recipes, lighting rules, and production-ready prompts for generating all visual assets in **Production: The Idle Game**.

All generated images must follow a hyper-realistic, documentary-grade industrial aesthetic (evoking high-end industrial photography from Bloomberg, National Geographic, and architectural journals like ArchDaily).

## 4. Prompt Generation Execution Tips

1. **Aspect Ratio:**
   * Facilities look best in landscape: `--ar 16:9` or `--ar 3:2`.
   * Products/commodities look best in 4:3 or 1:1: `--ar 1:1` or `--ar 4:3`.
2. **Upscaling:**
   * Standard generation resolution (e.g. 1024x1024 or 1344x768) should be upscaled once to 2K (e.g. 1920x1080) for crisp display in the Unit Detail dossier.
3. **File Format:**
   * Save as standard JPEG (`quality 90`) or WebP (`quality 85`).
4. **Instant Ingestion:**
   * The Unit Detail View (`frontend/js/ui/unitDetailView.js`) automatically binds the image filenames. The moment you place an image at `frontend/assets/images/facilities/{id}_facility.jpg`, it will seamlessly replace the default SVG blueprint placeholder on the facility page without code changes!
