// shiny_hunt.js — Find legendary buddies with specific eyes, hats, and shiny status
//
// Usage:
//   node shiny_hunt.js <species> [max_attempts]
//
// Examples:
//   node shiny_hunt.js cat              # Search 5M attempts
//   node shiny_hunt.js dragon 20000000  # Search 20M attempts
//
// Outputs every legendary match with full cosmetics,
// then a summary grouped by eye, hat, and shiny count.
