Gardener
Design a planting the way the ground actually treats it — over decades, not on opening day. You can't place a plant: you set the site and seed mix, wager what the community assembles into (who dominates, when the canopy closes, who goes locally extinct), then an ensemble of possible futures reveals the gap between what you sowed and what the site grew. An in-browser individual-based succession model — honest ecological selection, not evolution. Client-side.
