Interactive 3D swimming pool with flowers, ripples, rain, and whirlpool

GOAL: Build a single-file HTML + three.js interactive scene called "Bloom Pool": a sunlit swimming pool seen from a pitched perspective camera. MOTION: You drop tropical flowers onto the water and play with them. Pool and look: - A rounded-rectangle pool with a shallow end on the left and a deep end on the right. - Glassy mosaic tiles: a field, a border, and a band at the waterline. Each tile has a bevel and a soft glaze highlight. - Stone coping with a bullnose lip overhanging the water, deck pavers around it, and splash-darkened stone near the edge. - A dappled shadow from a palm crown leaning over one corner. - Size the pool and fit the camera to any screen, portrait or landscape. Water: - A real-time ripple heightfield updated at about 90 Hz. - Refraction of the tiled floor through the surface. - Animated Voronoi caustics on the floor. - Fresnel reflection of the sky and sun, and of the pool's own edge (the tiled wall band and the coping). - Crests and troughs, foam from splashes, a coping shadow and a meniscus along the walls. - Gentle circulation from the return jets. - Touch or drag across the water to make ripples. Flowers (five species, modeled procedurally from petal profiles): - White water lily: green sepals, three whorls of pointed petals. - Pink lotus: cupped petals around a seed pod and a ring of stamens. - Spotted tiger lily: six recurved tepals, long stamens. - Ruffled hibiscus: dark eye, long staminal column. - Waxy plumeria: a five-petal pinwheel. Each flower is a small physics body: - Drop it from a card at the bottom, or drag it over the water. It falls with turbulence and lands with a splash, droplets and rings. - It floats and bobs, radiating ripples. It glides with a wake, and floating flowers collide with each other. - A breeze turns them. They spin into a whirlpool. - Petals open and close on a spring, splay on impact and catch the airflow.
