Gemini Prompt: A young European female scientist stands in a modern laboratory, holding a small vial with pink liquid. She drinks it. Immediately after swallowing, she freezes for a brief moment — then a clearly visible physical transformation begins. Her body changes in three strong, separate pulses: Pulse 1: Her chest visibly increases in size, her top tightens across her torso, fabric stretching clearly. Pulse 2: Her chest expands further, becoming noticeably fuller and heavier, pushing against the fabric. Her posture straightens as her body adjusts. Pulse 3: Final, most powerful change — her chest reaches its full size, with strong visible tension in clothing and clear difference from the beginning. Each pulse creates a visible, undeniable difference, not subtle. Her breathing deepens, emphasizing movement. Her expression shifts from surprise to calm confidence. She looks down at her body, then slowly raises her gaze with a controlled, dominant look. Camera: fixed medium shot, no cuts, stable framing to clearly show the transformation. Bright realistic lighting. No fantasy effects.
