Sofia is Elena's inverse. Where Elena's system holds onto everything and recovers slowly, Sofia clears fast. Explosive power instead of endurance. Filtered perception instead of high gain. Fast metabolic clearance. Rapid stress recovery. Every axis pointing toward intensity and reset. She's not lucky or tougher than her friends. She's running completely different hardware.
