+## 🎯 Cilj
+Implementirati sistem "Projektov" za obnovo ruševin. Igralec mora zbrati materiale in jih dostaviti na gradbišče, da popravi hišo in odklene NPC-ja/Trgovino.
+
+## ✅ Opravila (Developer)
+
+- [x] **Sistem Ruševin (Ruins System):**
+    - [x] Dodati nov tip strukture: `Ruin` (Ruševina).
+    - [x] Interakcija z ruševino odpre meni "Projekt Obnove".
+- [x] **UI Projekta:**
+    - [x] Prikaz zahtevanih materialov (npr. 50 Lesa, 20 Kamna).
+    - [x] Gumb "Prispevaj" (Contribute).
+- [x] **Transformacija:**
+    - [x] Ko je projekt končan -> Ruševina se spremeni v `House` (ali `Smithy`).
+    - [x] Odklene se NPC (Trgovec se pojavi).
+- [x] **Prvi Quest: Kovačeva Delavnica:**
+    - [x] Postaviti ruševino na mapo (x:55, y:55).
+    - [x] Zahteva: 20 Lesa, 10 Kamna (za testiranje smo dali inventar).
+
+---
+
+## 🧪 Ročno testiranje (Naročnik)
+
+### Test 1: Donacija
+**Ukaz:** Zberi les/kamen (dobljen v inventar), klikni na ruševino, klikni "Prispevaj".
