Frozen-Time Couture Hall Portrait

Create a square 1:1 high-fashion editorial portrait set inside a grand luxury architectural hall with marble floors, towering Corinthian columns, ornate gold capitals, vaulted arches, and classical statues receding into the background. Show exactly 6 versions of the same glamorous blonde female model as if captured at different moments in one continuous runway walk, all wearing dramatic backless satin evening gowns with long flowing trains. The central present-time model is the largest and sharpest: she stands in the foreground, turned away with her back visible and head looking over her shoulder toward the viewer, wearing a metallic {argument name="main gown color" default="gold"} draped dress with a deep open back, glossy folds, and a long puddled train. Arrange 5 echo models around and behind her: left foreground in emerald green, left-mid in royal blue, center background in violet-purple, right-mid in deep magenta red, and right foreground in bright turquoise teal. Each echo model has the same blonde updo hairstyle and poised fashion-model posture, mostly viewed from the back or three-quarter back, creating a frozen-time visual echo effect. Use cinematic editorial lighting, polished marble reflections, warm museum-like highlights, ultra-detailed satin fabric, elegant realism, luxury magazine styling, dramatic depth, symmetrical palace architecture, and no text or watermark. The mood should feel like reality bending into pure fashion art, where every step creates a new couture moment.
