Detailed 16-bit pixel art masterpiece, isometric view of a magical underwater conservatory. A grand, crystalline dome rests on the serene ocean floor, its interior filled with a wondrous garden of fantastical, bioluminescent sea-flora. Plants shaped like glowing corals, crystalline ferns, and pulsing sea-anemones emit a soft, ethereal light in shades of cerulean, magenta, and gold. A graceful mermaid with flowing, deep-green hair and opalescent scales gently tends to the garden. Tiny, jellyfish-like sprites drift through the water-filled air inside the dome like fireflies. The lighting is magical and serene, primarily from the glowing flora, creating a vibrant, high-contrast scene with deep, soft shadows. Through the thick glass of the dome, the deep, mysterious blue of the open ocean is visible, with the faint silhouette of a giant manta ray gliding by in the distance. The overall mood is one of tranquility, wonder, and hidden magic. Rich color palette, intricate details, clean pixel work, masterful dithering.
