Festival of Lights Celebration Poster Prompt — Diwali Diya Art (4:5)

Create a 4:5 portrait festival poster celebrating [FESTIVAL] with the greeting "[GREETING]". Composition: a deep midnight-blue night scene where dozens of glowing clay diyas float on dark rippling water, their warm flames reflected in long shimmering trails; marigold garlands draped across the top corners in rich orange and gold; faint bokeh fireworks in the distant sky. Typography: the greeting in large gold-foil serif with a subtle metallic sheen across the upper third, festival name in letterspaced caps beneath, and a small blessing line at the bottom in soft cream. Lighting: dramatic chiaroscuro — the diyas are the only light source, warm glow falloff into the dark. Style: premium festive key art, rich cinematic color, ultra-detailed, no watermark.
