+# 46. 상점 시스템 리팩토링 및 예외 처리 (Shop System Refactoring & Error Handling)
+
+## 1. 목표 (Goal)
+- `BattleProvider`에 집중된 상점 관련 로직을 `ShopProvider`로 분리하여 **관심사의 분리(Separation of Concerns)**를 실현합니다.
+- 아이템 획득(보상/구매) 시 인벤토리 가득 참이나 골드 부족 등의 예외 상황에 대해 명확한 에러 메시지(UI 피드백)를 제공합니다.
+
+## 2. 구현 상세 (Implementation Details)
+
+### A. 상점 로직 분리 (`ShopProvider`)
+- **파일:** `lib/providers/shop_provider.dart` 생성.
+- **이동된 기능:**
+  - `generateShopItems`: 스테이지 티어에 따른 상점 아이템 목록 생성.
+  - `rerollShopItems`: 골드 소모 후 아이템 목록 갱신.
+  - `buyItem`: 골드 차감 및 인벤토리 추가 로직.
+- **구조 변경:**
+  - `BattleProvider`는 더 이상 `BuildContext`를 직접 참조하거나 상점 상태를 관리하지 않습니다.
+  - `main.dart`에서 `ChangeNotifierProxyProvider`를 사용하여 `ShopProvider`를 `BattleProvider`에 주입(Injection)합니다.
+
+### B. 예외 처리 및 UI 피드백
+- **반환값 변경 (`bool`):**
+  - `BattleProvider.selectReward`: 인벤토리 가득 찰 시 `false` 반환.
+  - `ShopProvider.buyItem`: 골드 부족 또는 인벤토리 가득 찰 시 `false` 반환.
+- **UI 반영 (`BattleScreen`, `ShopUI`):**
+  - 메서드가 `false`를 반환할 경우 `ScaffoldMessenger`를 통해 붉은색 `SnackBar`로 에러 메시지를 출력합니다.
+  - 예: "Inventory is full! Cannot take item.", "Purchase failed! Check inventory or gold."
+
+## 3. 결과 (Result)
+- **코드 품질:** 거대해지던 `BattleProvider`의 책임을 분산시켜 유지보수성을 높였습니다.
+- **안정성:** `BattleProvider`의 `BuildContext` 의존성을 제거하여 잠재적인 컨텍스트 관련 오류를 해결했습니다.
+- **사용자 경험:** 아이템 획득 실패 시 명확한 피드백을 제공하여 답답함을 해소했습니다.

+# 47. 인벤토리 가득 참 처리 (Inventory Full Handling)
+
+## 1. 목표 (Goal)
+- 인벤토리가 가득 찬 상태(`maxInventorySize`)에서 보상 아이템 획득을 시도할 경우, 게임이 진행되지 않고 에러 메시지를 표시합니다.
+- 보상 팝업이 닫히지 않도록 하여 사용자가 다른 행동(스킵 또는 인벤토리 관리)을 할 수 있게 합니다.
+
+## 2. 구현 상세 (Implementation Details)
+
+### `BattleProvider` 수정
+- **`selectReward` 메서드 반환값 변경:** `void` -> `bool`.
+  - **성공 (아이템 획득 또는 스킵):** `true` 반환. 스테이지 클리어 로직 진행.
+  - **실패 (인벤토리 가득 참):** `false` 반환. 스테이지 클리어 로직 중단. 로그만 남김.
+
+### `BattleScreen` 수정
+- **보상 선택 로직:**
+  - `battleProvider.selectReward(item)`의 반환값을 확인.
+  - `false`일 경우 `ScaffoldMessenger`를 사용하여 "Inventory is full! Cannot take item." 스낵바 출력.
+
+## 3. 결과 (Result)
+- 인벤토리가 가득 찼을 때 실수로 아이템이 버려지거나 다음 스테이지로 강제 진행되는 문제를 방지했습니다.
+- 사용자에게 명확한 피드백(에러 메시지)을 제공합니다.

+# 48. Stage UI 구조 개선 (Refactor Stage UI Structure)
+
+## 1. 목표 (Goal)
+- `lib/widgets/battle/stage_ui.dart`에 혼재되어 있던 `ShopUI`와 `RestUI`를 분리하여 `lib/widgets/stage/` 폴더 내의 독립적인 파일로 관리합니다.
+- 코드의 가독성과 모듈화를 향상시킵니다.
+
+## 2. 구현 상세 (Implementation Details)
+
+### 폴더 및 파일 생성
+- **폴더:** `lib/widgets/stage/`
+- **파일 분리:**
+  - `lib/widgets/stage/shop_ui.dart`: 상점 UI 관련 코드 이동.
+  - `lib/widgets/stage/rest_ui.dart`: 휴식 UI 관련 코드 이동.
+
+### 코드 수정 (Code Updates)
+- **기존 파일 삭제:** `lib/widgets/battle/stage_ui.dart` 삭제.
+- **참조 수정:** `BattleScreen` 등에서 `stage_ui.dart`를 참조하던 부분을 새로운 경로(`shop_ui.dart`, `rest_ui.dart`)로 업데이트.
+
+## 3. 결과 (Result)
+- 상점과 휴식 스테이지 UI가 물리적으로 분리되어 관리가 용이해졌습니다.
+- 프로젝트의 위젯 구조가 기능별로 더욱 명확하게 정리되었습니다.

+# 52. 아이템 아이콘 이미지 적용 (Item Icon Image Implementation)
+
+## 1. 목표 (Goal)
+- 기존의 머티리얼 아이콘(`IconData`) 대신 `assets/data/icon/`에 추가된 PNG 이미지 아이콘을 UI에 적용합니다.
+- `ItemUtils`를 수정하여 아이콘 경로를 반환하도록 변경하고, 주요 UI 화면(`BattleScreen`, `InventoryScreen`, `ShopUI`)에서 `Image.asset`을 사용하도록 리팩토링합니다.
+
+## 2. 구현 상세 (Implementation Details)
+
+### 에셋 등록
+- `pubspec.yaml`에 `assets/data/icon/` 경로 추가.
+
+### `ItemUtils` 수정
+- `getIcon(EquipmentSlot)` 제거 (또는 사용처 변경).
+- `getIconPath(EquipmentSlot)` 메서드 추가: 장비 슬롯별 이미지 파일 경로 반환.
+  - Weapon -> `icon_weapon.png`
+  - Shield -> `icon_shield.png`
+  - Armor -> `icon_armor.png`
+  - Accessory -> `icon_accessory.png`
+
+### UI 수정 (Icon -> Image.asset)
+- **`ShopUI` (`lib/widgets/stage/shop_ui.dart`):** 상점 아이템 카드의 아이콘 교체.
+- **`InventoryScreen` (`lib/screens/inventory_screen.dart`):**
+  - 착용 중인 아이템 슬롯의 아이콘 교체.
+  - 인벤토리 그리드 내 아이템 아이콘 교체.
+- **`BattleScreen` (`lib/screens/battle_screen.dart`):**
+  - 스테이지 클리어 보상 팝업의 아이템 아이콘 교체.
+  - **플로팅 액션 버튼(FAB):** ATK/DEF 버튼의 아이콘을 `icon_weapon.png`와 `icon_shield.png`로 교체하고 흰색 틴트 적용.
+
+## 3. 결과 (Result)
+- 게임 내 아이템 표현이 단순 기호에서 구체적인 이미지로 변경되어 시각적 몰입도가 향상되었습니다.
+- `ItemUtils`를 통해 아이콘 자원 관리가 중앙화되었습니다.
