- Implemented new navigation system with NavigationProvider and route management
- Added adaptive theme system with ThemeProvider for better theme handling
- Introduced glassmorphism design elements (app bars, scaffolds, cards)
- Added advanced animations (spring animations, page transitions, staggered lists)
- Implemented performance optimizations (memory manager, lazy loading)
- Refactored Analysis screen into modular components
- Added floating navigation bar with haptic feedback
- Improved subscription cards with swipe actions
- Enhanced skeleton loading with better animations
- Added cached network image support
- Improved overall app architecture and code organization

+## 구독관리 앱 글래스모피어즘 색상 가이드  
+**신뢰성, 편안함, 트렌드함**을 모두 잡는 컬러 조합 추천
+
+### 1. 컬러 선정 원칙
+
+- **신뢰성:** 블루 계열, 그레이, 화이트 등 안정적이고 전문적인 느낌의 색상
+- **편안함:** 저채도 파스텔, 연한 블루·민트, 따뜻한 베이지 등 눈에 부담 없는 색상
+- **트렌드함:** 그라디언트, 반투명 레이어, 약간의 네온 포인트 등 현대적 감각
+
+### 2. 추천 컬러 팔레트
+
+| 용도         | 추천 색상 예시 (Hex)           | 설명                                  |
+|--------------|-------------------------------|---------------------------------------|
+| 메인         | #2563eb, #60a5fa, #e0e7ef     | 신뢰감 주는 블루 계열 그라디언트      |
+| 서브         | #f9fafb, #f1f5f9, #f3f4f6     | 밝은 화이트·그레이, 편안한 배경       |
+| 포인트       | #38bdf8, #7dd3fc, #f472b6     | 트렌디한 민트, 연핑크, 밝은 블루      |
+| 테두리/블러  | rgba(255,255,255,0.3)         | 글래스 효과용 반투명 화이트           |
+| 그림자       | rgba(0,0,0,0.08)              | 부드러운 깊이감 부여                  |
+
+### 3. 실전 적용 예시
+
+- **배경:**  
+  연한 블루(#e0e7ef) 또는 밝은 그레이(#f9fafb)  
+- **글래스 카드:**  
+  반투명 화이트(예: rgba(255,255,255,0.2)), 블루 그라디언트 테두리  
+- **포인트 버튼:**  
+  밝은 민트(#38bdf8) 또는 연핑크(#f472b6)  
+- **아이콘/텍스트:**  
+  진한 블루(#2563eb), 다크 그레이(#334155)  
+- **그라디언트 예시:**  
+  LinearGradient(  
+    begin: Alignment.topLeft,  
+    end: Alignment.bottomRight,  
+    colors: [Color(0xFF2563eb), Color(0xFF60a5fa), Color(0xFFe0e7ef)],  
+  )
+
+### 4. 참고 팁
+
+- 글래스모피어즘은 **투명도·블러**와 함께 **밝고 깨끗한 색상**을 조합하면 신뢰감과 트렌디함을 동시에 줄 수 있습니다.
+- 포인트 컬러를 너무 강하게 쓰기보다는, 전체적으로 **밝고 부드러운 톤**에 약간의 컬러만 더하는 것이 편안함을 극대화합니다.
+- 실제 인기 앱(Reflect, T.RICKS, Coffee 등)도 블루·화이트·민트 계열을 주로 활용합니다.
+
+### 5. 컬러 팔레트 예시
+
+| 이름        | Hex 코드   | 용도/느낌         |
+|-------------|------------|-------------------|
+| Deep Blue   | #2563eb    | 신뢰, 메인        |
+| Sky Blue    | #60a5fa    | 트렌드, 그라디언트|
+| Soft Mint   | #38bdf8    | 포인트, 상쾌함    |
+| Light Gray  | #f1f5f9    | 배경, 편안함      |
+| White Glass | #ffffff(투명도) | 글래스 효과   |
+| Pink Accent | #f472b6    | 포인트, 트렌디    |
+
+### 6. 마무리
+
+- **블루+화이트+민트** 조합은 신뢰성, 편안함, 트렌드함을 모두 만족시킵니다.
+- 글래스모피어즘 효과와 함께라면, 위 팔레트로 세련되고 현대적인 구독관리 앱 UI를 완성할 수 있습니다.  
+- 실제 적용 시, 밝은 배경과 부드러운 그라디언트, 포인트 컬러를 적절히 조합해보세요.
