Anhinga Wetland Diving Lab (2D): Buoyancy, Drag & Wing-Drying

2D side-view anhinga physics lab: real Archimedes buoyancy from wettable plumage, a drag-vs-thrust underwater pursuit model for spearing fish, and a wing-drying timer that gates takeoff.

This 2D companion strips the anhinga's underwater hunt down to the physics that actually drives it: real Archimedes-principle buoyancy computed from body volume against water-absorbed feather weight (the "feather wettability" slider), a quadratic drag-vs-thrust swimming model for the pursuit of a fleeing fish, and a wing-drying timer that genuinely gates takeoff — because unlike a duck's oiled plumage, an anhinga's wettable feathers soak through, and it must dry them before it can fly.
