🎯 BALLISTIC TRAJECTORY ENGINE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Powered by a 3-Degree-of-Freedom (3-DOF) Runge-Kutta 4th order numerical solver — the same class of solver used by professional-grade ballistic software. No simplified formulas. Real physics.

• G1 and G7 drag models supported
• Adaptive time-step integration for maximum accuracy
• Atmospheric density correction (temperature, pressure, humidity, altitude)
• Speed-of-sound correction
• Coriolis effect compensation
• Gyroscopic spin drift correction
• Shooting angle (incline/decline) compensation

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📊 COMPLETE BALLISTIC SOLUTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Enter your inputs once and get a full firing solution instantly:

• Bullet drop in MOA or MRAD
• Windage correction (Left/Right)
• Velocity at target (fps)
• Time of flight (seconds)
• Energy at impact (ft-lbs)
• Full range table from muzzle to max distance
• Trajectory chart with interactive bullet drop curve

🔫 FLEXIBLE INPUT SYSTEM
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Organised into 4 clear input tabs:

ATMOSPHERE — Temperature, pressure, humidity, altitude, shooting angle
RIFLE — Zero range, scope height, click value (MOA/MRAD), rifle profiles
PROJECTILE — Bullet weight, ballistic coefficient, drag model, muzzle velocity
TARGET — Target distance, wind speed and direction, ammunition profiles

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🗂️ PROFILE MANAGEMENT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Save and manage your equipment:

• Rifle profiles — zeroing data, scope height, click values
• Ammunition profiles — bullet weight, BC, muzzle velocity, drag model
• Instantly swap between different setups in the field

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
⚙️ SETTINGS & UNITS
