Iridescent dotted map and 3D globe look

Iridescent applies a Fresnel-driven HSV cycle across the dot field, with procedural sparkle layered on top. The result reads as holographic foil, pearlescent paint, or fish-scale shimmer depending on the motion setting. It's the awwwards-2026 darling, the same general aesthetic showing up across modern product launches, Y2K-revival brand systems, and credit-card / membership-card marketing. The hue cycles over time (paused under prefers-reduced-motion), and the cellSize control tunes sparkle density. Pair Iridescent with the globe view for hero graphics that feel premium and contemporary.
