  # Day 10: Factory Machines
  # Part 1: Configure indicator lights (binary toggle) - minimize button presses
  # Part 2: Configure joltage counters (integer addition) - minimize button presses
  #
  # Solution requires:
  # - Gaussian elimination over GF(2) for Part 1
  # - Integer linear programming for Part 2
  # - Enumeration of free variable combinations
  #
  # This is too complex for pure Nix - see TypeScript solution
