Soil fertility scales calendar-driven plant growth
Bump the engine submodule to f39ee9e (half-texel UV inset that removes the black tile seams seen while zooming). Add a Fertility multiplier to TerrainDef (forest soil rich, sand/mountain poor); plants record their cell's fertility as PlantGrowth.GrowthRate at spawn, and the growth system multiplies the per-frame calendar day-delta by it — so growth stays tied to the in-game calendar and runs faster on fertile soil.
