🟤 Propolis Envelope: Hive-Wall Sealing & Its Biological Payoff (2D)

This 2D companion turns the "propolis envelope" behaviour shown in the 3D hive interior into a driven cause-and-effect model: a cutaway hive-wall cross-section is seeded with a randomised set of gaps, worker bees are assigned to open gaps and close them at a rate set by their resin-collection rate, and the resulting sealed-coverage percentage drives two real outcome curves — a pathogen-intrusion rate that falls as sealing proceeds, and a wall heat-loss figure that falls with the same open-area term — so changing worker count, resin rate or the initial gap layout visibly changes how fast the colony's hygiene and thermal protection actually improve.
