Create a hyper-realistic tourism advertisement collage in a single 1:1 square image divided into a 2x2 grid. Each panel shows a hand holding a sleek, ultra-thin portrait smartphone, slightly tilted for a strong 3D portal effect, with iconic national food emerging from the screen into the real world. Top-left France: golden buttery croissant with strawberries, Eiffel Tower background. Top-right Italy: hot pizza with basil and steam, Colosseum sunset background. Bottom-left Japan: assorted sushi and sashimi. Keep consistent hand, phone design and lighting.
