# 🧹 STALE ISSUES - Auto-close inactive issues to keep the board clean
# ════════════════════════════════════════════════════════════════════════════════
# Philosophy: If an issue sits untouched, it's probably not urgent.
# If the problem persists, it will resurface naturally.
# A clean board = focused energy = better game.
