Each enemy is a Transform-only root with a body child (rotates to face you, on the world layer). Nameplates and health bars are independent entities tracked via ScreenFollow: each frame it projects the enemy's world position through the camera and writes the screen coord to the UI entity's Transform. A UIPanel with positioning: "transform" on the screen-space UI layer reads that coord — so the UI tracks the enemy while staying axis-aligned and constant-size as the camera zooms and rotates.
