AI Video Prompt: Magical Desert Portal Door on Tropical Beach

A hyper-realistic, cinematic vertical video (9:16) of a surreal magical portal. The camera is completely static and locked-off. In the center of a pristine white sandy tropical beach, a weathered, dark wooden door with a brass handle stands freestanding. Behind the door is a beautiful turquoise ocean with gentle waves and a clear blue sky. The door slowly and smoothly swings open inward (away from the camera). As it opens, it reveals that it is a portal to another dimension: inside the doorframe is a vast, glowing desert with rolling golden sand dunes under a warm, hazy sky. The door opens fully to a 90-degree angle. Outside, the cool ocean waves gently wash around the base of the door in the sand. High contrast between the cool blue beach and the warm orange desert. Deep 3D depth inside the portal, realistic water interaction with the door base, soft golden hour lighting, 8k resolution, highly detailed.
