Three Holographic Anime Idols on Stage

Create a wide 16:9 anime idol concert scene on a futuristic holographic stage, featuring exactly three young female virtual pop idols standing in a row and performing synchronized choreography with one arm raised straight upward and index finger pointing to the sky. The center idol is the lead, slightly closer to camera, with {argument name="center idol hair color" default="long pastel pink twin tails"}, soft pink eyes, and a gentle confident smile. The left idol has {argument name="left idol hair color" default="short blonde bob hair"} and a warm smile. The right idol has {argument name="right idol hair color" default="short black hair with vivid blue highlights"}, one eye partly hidden by bangs, and a cool expression. All three wear matching {argument name="outfit style" default="dark navy starry holographic mini dresses"}: glossy corset bodices with sweetheart necklines, sheer long black sleeves, ruffled short skirts, sparkling constellation-like star patterns, small star ornaments at the chest, black chokers, wrist cuffs, and thigh-high dark stockings with star details. The stage background is a grand sci-fi concert hall with glowing blue crystalline arches, circular metallic structures, rows of tiny lights, sweeping white laser beams, misty cyan holograms, and faint carousel-like horse silhouettes or cosmic projections behind them. Use luminous blue and violet lighting, high-energy J-pop live performance atmosphere, glossy reflections, cinematic depth of field, soft bloom, detailed anime rendering, polished GPT-image style, no visible text, no watermark, no extra performers beyond the three idols.
