🏗️ Landfill Cell Compaction: Lift-by-Lift Settlement and Airspace Recovery Lab

Fill a landfill cell lift by lift in a 3D cutaway. Compactor passes set density, overburden stress drives primary compression, and decay-driven secondary settlement follows a log-time law, giving back airspace that can be refilled. Includes a compaction sweep, a century-long settlement forecast and independent closed-form checks.
