docs(10_Wiki): 위키 구조 정리 — 언어 튜토리얼 카테고리 폴더 제거 + 신규 자산 동기화

Topic_CSS/Topic_HTML/Topic_JavaScript/Topic_Prompt/Topic_Comfyui 등 기존 카테고리 폴더를 정리하고, Topic_Graphic/Dev 등 신규 산출물과 Topics 내부 세션/메모리 기록을 동기화.

+# [[CPP Constants]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Just like in C, `const` requires initialization at the MOMENT of declaration — declaring `const int minutesPerHour;` and assigning it a value on a later line is explicitly shown to fail — meaning C++ inherits C's exact same "declare-without-assign is illegal for const" restriction rather than relaxing it. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **`const` keyword** — declares a variable as unchangeable/read-only after initialization. [S1]
+- **Mandatory initialization** — a `const` variable must receive its value at declaration time; assigning it later is a compile error. [S1]
+- **Use case** — values unlikely to ever change (e.g. `minutesPerHour`). [S1]
+
+## 📖 세부 내용 (Details)
+- Attempting reassignment fails: `const int myNum = 15; myNum = 10; // error: assignment of read-only variable 'myNum'`. [S1]
+- Declare-without-assign fails: `const int minutesPerHour; minutesPerHour = 60; // error`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- **C와 동일한 const 초기화 규칙**: 선언과 동시에 값을 할당해야 하며, 나중에 대입하는 방식은 에러가 발생한다는 점이 C 챕터와 완전히 동일함이 확인됨. [S1]
+
+## 🛠️ 적용 사례 (Applied in summary)
+현재 발견된 실제 적용 사례가 없습니다 — 절대 변하지 않는 값(예: minutesPerHour = 60)을 const로 선언하는 것이 실전 코드의 표준 활용이다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Declaring a constant that must be initialized at the point of declaration (C++):
+```cpp
+const int minutesPerHour = 60;
+```

+## ✅ 검증 상태 및 신뢰도
+- **상태:** draft
+- **검증 단계:** conceptual
+- **출처 신뢰도:** B (W3Schools — widely used educational reference, not a primary standards body)
+- **신뢰 점수:** 0.84
+- **중복 검사 결과:** 신규 생성 (New discovery)
+
+## 🔗 지식 그래프 (Knowledge Graph)
+- **상위/루트:** [[C++ Tutorial]]
+- **관련 개념:** [[CPP Variables Identifiers]], [[CPP Variables Multiple]], [[C Constants]]
+- **참조 맥락:** 상수 선언 — 여러 변수 한번에 선언하기(Variables Multiple) 챕터로 이어짐.
