Turn the aisle around me into a planetarium

Use my uploaded user photo in a shop or ordinary corridor. Preserve my source appearance, product layout, shelf labels, prices and floor geometry. Before sharing, use a synthetic source or confirm consent for identifiable shoppers; otherwise crop or mask them. Transform only [CEILING OR EMPTY WALL AREA] into a convincing projected planetarium with [CELESTIAL SCENE], allowing restrained reflected light on surrounding surfaces but none across the face. Retain the perspective lines and existing fixtures. Output one composite plus a mask description that distinguishes factual content from projection. No altered prices, invented store branding, extra people or astronomy labels that appear factual without verification. Inspect the projection mask, original shop information and every visible bystander before sharing.
