🌊 Buoyancy Glider Sawtooth Dive: Lift, Drag and Battery (2D section)

Side section of an autonomous underwater glider: an oil bladder changes buoyancy, fixed wings turn the vertical motion into forward glide, and the path is a sawtooth between two turn depths. Same RK4 solver as the 3D page, with force-balance, energy-ledger and Archimedes checks.
