POV Smartphone with Space-Themed Twitter UI in Central Park

Capture a photograph from the viewer’s eyes (female), holding a modern smartphone at chest height with both hands. Her nails are glossy red nail polish with a clean manicure. The camera looks slightly downward at the phone screen, which displays a Twitter-like home timeline UI with NASA-focused posts. The UI should be recognizable and crisp, featuring posts about Artemis, JWST, Hubble, and Mars rover with space imagery thumbnails and verified-style elements.
