Art style: Flat motion graphics animation.
A young woman with fair skin, bright blonde hair tied back in a high ponytail, and expressive blue eyes. She wears a teal athletic shirt and dark red leggings. Her build starts as healthy and athletic but becomes gaunt, with sunken cheeks and dark circles under her eyes as the story progresses. The background is a simple, light blue with faint scientific doodles like beakers and DNA strands.
