// @namespace    https://scriptneo.com/
// @version      1.0.0
// @description  Auto plays your Grarrl Keno. Supports Quick Pick (double click to finalize) or Random eggs (no duplicates, optional no-adjacent). Forces bet, waits for hatch, loops, persists settings, and logs prize_chart winners numbers one line per round once all 10 numbers exist.
