ご指摘ありがとうございます。黄色の線分（姿勢）が誤って降下線に沿ってしまっていたように見えた問題（あるいは回転軸の挙動）を修正し、「初期値は完全にX軸と平行（水平）」になるようロジックを見直しました。
また、円柱の生成時の原点（ジオメトリの中央）を利用することで、「線分の中央を軸としてY軸回転する専用スライダー」として独立・明確化しました。
運用ルールに従い、まずは初期設定ブロックを出力します。
---
## 1. 初期設定ブロック（コピー用）
機体姿勢用の角度設定変数 `LINE_PITCH_DEFAULT` を明記し、0.0度（X軸平行）を初期値としています。
```python
# =========================================================
# 6. 初期設定
# =========================================================
# 数値・座標
START_X_DEFAULT = -100.0 # 開始地点のX座標
LANDING_ANGLE_DEFAULT = 30.0 # 初期降下角度（度）
# サイズ (半径・長さ)
RADIUS_CYLINDER_DEFAULT = 0.5 # 降下軌道（円柱）の太さ
RADIUS_SPHERE_DEFAULT = 1.5 # 飛行機（現在位置・球体）の大きさ
RADIUS_TARGET_DEFAULT = 2.0 # 着地点の大きさ
LENGTH_LINE_DEFAULT = 2.0 # 線分の初期全長
# 角度
LINE_PITCH_DEFAULT = 0.0 # 線分の初期Y軸回転角度（0.0でX軸に完全平行）
# 色 (R, G, B, A)
# ※ A(アルファ)を1.0未満にすると半透明になります
COLOR_GLIDE_PATH = (0.0, 0.5, 1.0, 0.3) # 軌道（青・半透明）
COLOR_AIRPLANE = (1.0, 0.0, 0.0, 1.0) # 飛行機（赤）
COLOR_TARGET = (0.0, 1.0, 0.0, 1.0) # 着地点（緑）
COLOR_LINE = (1.0, 1.0, 0.0, 1.0) # 姿勢線分（黄）
NパネルのUI上で「機体姿勢（線分）」の回転スライダーを独立した枠（ボックス）で囲み、スライダーを動かすと線分の中央を軸にしてY軸回転するように調整しています。
