/**
 * MilkyWaySystem - The Hero Element
 *
 * Creates a luminous river of stars across the sky with:
 * - Multi-layer gradient rendering (like fish iridescence)
 * - Dark dust lanes with organic edges (like jellyfish mesoglea)
 * - Bright star clusters with pulsing (like bioluminescence)
 * - Traveling shimmer wave across the band
 * - Organic edge variation using seed arrays (like dappled light rays)
 *
 * Visual approach inspired by Deep Ocean's techniques:
 * - Every element has multiple independent animation phases
 * - Multi-layer gradients create depth
 * - Seed-based organic variation prevents geometric feel
