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 Variables Examples]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+The same admission from C's equivalent chapter appears here verbatim — the tutorial explicitly acknowledges its OWN convention of type-based names (`myInt`, `myChar`) is an artificial teaching simplification "to avoid confusion," and this chapter exists specifically to demonstrate the alternative: naming variables after what they REPRESENT (`studentID`, `studentGrade`) in a realistic multi-type program. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Type-based teaching names vs. domain names** — tutorial examples simplify names to match type for clarity, but real programs should name variables after their real-world meaning. [S1]
+- **Multiple types working together** — one program combining `int`, `double`, and `char` variables representing facets of one entity (a student record). [S1]
+- **Calculate-then-print pattern** — compute first, store the result, then print — same pattern as C's equivalent chapter. [S1]
+
+## 📖 세부 내용 (Details)
+- Student record combining three types: `int studentID = 15; int studentAge = 23; double studentFee = 75.25; char studentGrade = 'B';` printed via chained `cout <<` statements. [S1]
+- Rectangle area calculate-then-print: `int length = 4; int width = 6; int area = length * width; cout << "Area of the rectangle is: " << area << "\n";`. [S1]
+
+## ⚖️ 모순 및 업데이트 (Contradictions & updates)
+- 현재까지 발견된 모순 사항 없음 (No contradictions found in available sources).
+
+## 🛠️ 적용 사례 (Applied in summary)
+학생 정보(ID/나이/수수료/학점)를 하나의 프로그램에서 함께 다루는 예제가 서로 다른 타입의 변수를 실제 데이터 모델링에 사용하는 대표 사례다. [S1]
+
+## 💻 코드 패턴 (Code patterns)
+Calculating a value first, then printing the stored result (C++):
+```cpp
+int length = 4;
+int width = 6;
+int area = length * width;
+cout << "Area of the rectangle is: " << area << "\n";
+```
