"""D03 길이·기울기 고정 부채꼴 셈(PLAN 625-2 · 요구 530 · 531 B1~B7) — TS `logic/D03_PlanAnalysis_Fan.ts` 순수 시험.

화면 고르기 전용(파이썬 짝 없음) — tsc 로 옮겨 Node 로 돌림.
- 경사면 65 % · 반지름 20 m · 9 % = 노드 4 · 호 2 · 호마다 + 하나 − 하나 · 부채꼴 폭 ≈ 2·arcsin(9/65).
- 꽃잎 땅 cos(nθ) = 노드 2 · 4 · 6 · 8 · 호 n.
- 정방향 = 앞 구간 쪽 호 · 첫 구간 없음 · 거의 같으면 마우스 쪽.
- 완만한 땅 = 노드 0 · 어느 방향이나 · Shift 사이 = 길이 그대로 · 기울기 = 실제 지형 · 호 밖 = 호 끝.
