Photoreal cinematic still in the bright sunny family living room from the reference image (herringbone oak floor, olive-green walls, oak staircase, white sofa), nobody in the room. In the middle of the room, hovering just above the floor, a sleek modern portal: a perfectly thin razor-sharp ring of white-cyan light, about two meters tall, and inside it a vertical membrane like rippling liquid glass that refracts the room, and through it a glimpse of a deep turquoise underwater world with sunbeams and glowing jellyfish. Elegant, minimal, premium, high-end VFX, soft caustic light patterns spilling onto the floor and walls, subtle chromatic aberration at the ring edge. Not a swirl, not a vortex, no cartoon spiral.
