Years of research, countless sleepless nights, all culminating in this…this masterpiece. A low chuckle escaped her lips. The grant committee would be floored.

A notification pinged. An email from Dr. Chen, her nemesis from the rival university. Curious, Amelia opened it. The subject line: "Project Phoenix - Update." Her breath hitched. Inside, a link. She clicked, fingers trembling slightly. The page loaded. The same arm. The *exact* same arm. Her mouth fell open.
