+# 🏗️ BLUEPRINT SYSTEM & ITEM VISUALIZATION
+
+**Owner:** David Kotnik
+**Created:** 20.01.2026
+**Status:** Active
+
+---
+
+## 🎯 CORE CONCEPT
+The game uses a dual-visualization system for all items:
+1.  **ITEMS (`assets/slike/items/`)**: Full-color, solid sprites. Used in Inventory, Shops, Drop Items.
+2.  **BLUEPRINTS (`assets/slike/items/blueprints/`)**: Semi-transparent, holographic "ghost" versions. Used in Build Mode, Placement Preview.
+
+## 📂 FOLDER STRUCTURE
+The `blueprints/` folder **mirrors** the `items/` folder structure exactly.
+
+```
+assets/slike/items/
+├── tools/
+│   ├── axe.png          (Original)
+│   └── hoe.png
+└── blueprints/          <-- AUTO-GENERATED MIRROR
+    └── tools/
+        ├── axe.png      (Ghost version)
+        └── hoe.png
+```
+
+## 🤖 AUTO-GENERATION RULE
+**Agent Instruction:**
+When the User adds a new image to `items/`, you MUST immediately run:
+`python3 scripts/generate_blueprints.py`
+
+This script will seamlessly verify all items and generate missing blueprints.
+
+## 💻 CODING STANDARD (Clean Code)
+Logic must explicitly distinguish between **Inventory Context** and **Construction Context**.
+
+### ✅ CORRECT USAGE:
+```javascript
+import { ItemManager } from '../managers/ItemManager';
+
+const itemManager = new ItemManager(this);
+
+// 1. KAI OPENS BACKPACK (Inventory)
+// Use normal image
+const icon = itemManager.getItemImagePath('tools/axe.png', false); 
+
+// 2. KAI IS BUILDING (Construction)
+// Use blueprint/ghost image
+const preview = itemManager.getItemImagePath('tools/axe.png', true);
+```
+
+### ❌ INCORRECT USAGE:
+- Hardcoding paths like `assets/slike/items/blueprints/...` manually.
+- Using opacity/alpha on normal sprites to simulate blueprints (Performance heavy, looks worse).
+- Checking for blueprints existence manually (Trust the auto-gen script).
