/**
* Gon Low Grappling Guard Pose - OVERHAULED
*
* **Korean**: 땅 방어 (Ttang Bangeo)
* **Philosophy**: HEAVY low guard position for wrestling engagement
*
* **IMPROVED Features:**
* - **Deeper Stance**: -55° knee bend (was -50°) for more grounded feel
* - **Lower Height**: -18cm pelvis (was -15cm) creating heavier impression
* - **Wider Base**: 1.3x shoulder width (was 1.2x) for more stability
* - **Heavy Weight**: 27° ankle dorsiflexion (was 20°) showing loaded feet
* - **Lower Hands**: 35° shoulder flexion (was 30°) for deeper grappling ready
*
* Characteristics:
* - Hands low and forward for IMMEDIATE grappling grabs
* - Knees DEEPLY bent for VERY low center of gravity
* - Hips back ready to sprawl or shoot explosively
* - Head up maintaining posture and awareness
* - Weight HEAVILY loaded on feet - ROOTED feel
*
* Biomechanics:
* - Stance width: 1.3x shoulder width (WIDER stable base)
* - Pelvis height: -18cm (LOWER center of gravity)
* - Knee bend: -55° (DEEPER athletic position)
* - Hip position: -25° (hips back MORE for stability)
* - Ankle dorsiflexion: 27° (HEAVY weight loading)
