Romantic Mediterranean cliffside staircase at blue hour

Creat image Vertical 9:16 frame, ultra-realistic cinematic travel photography of a luxurious whitewashed Mediterranean coastal staircase winding gracefully down a steep seaside cliff during peaceful blue hour. Smooth curved white stucco walls frame the wide descending steps, with warm amber recessed lights glowing along every stair and pathway edge. Elegant vintage lanterns with bright candlelight stand at different levels beside the staircase, creating a rich romantic atmosphere. Dense cascading bougainvillea flowers in vivid magenta, fuchsia, and deep purple completely cover the overhead branches, cliffside walls, and garden borders, with large abundant flower clusters hanging close above the walkway. Every bougainvillea bloom features three large delicate papery bracts surrounding a tiny, crisp pure-white tubular true flower at the center. The bright white centers are clearly visible on every blossom, creating beautiful natural contrast and authentic botanical realism. To the left, a calm deep-blue sea stretches toward dark mountainous islands on the horizon, with a small white sailboat resting near the distant shoreline. Soft lavender, pink, and pale-blue twilight sky, tranquil water reflections, realistic stone and plaster textures, vivid saturated colors, luxurious coastal resort atmosphere, extremely sharp details, smooth clean photorealistic 8K quality.
