Photoreal Swamp Inside a Space Colony Dome

Photorealistic render of a swamp inside a massive space colony biosphere. A murky, shallow swamp fills the floor, with thick, knotted mangrove-like roots, lily pads, reeds, and bioluminescent algae illuminating the water in green-blue tones. The swamp is contained by a transparent glass dome with a curved observation deck and metal railings above the water. A few colonists in sleek space suits and helmets study the ecosystem, holo-displays projecting data from their wrists. In the background, modular habitat corridors, piping, and glass-walled work bays wind through the chamber. Soft blue-white artificial lighting mixes with warm amber bioluminescence from plants, creating ribbons of light through creeping mist that rises from the water. Realistic textures: muddy banks, wet bark, moss, rain droplets on glass, ripples on water, and subtle reflections. Cinematic, ultra-realistic detail, 8K quality, depth of field.
