🌿 Orchard Phenology

18 real, named fruit/nut/citrus/vine species planted in a real grid at Central Valley, California (36.75°N, 119.77°W), living through the real calendar year starting 1999-01-01. Day length, sunrise/sunset and the sun's noon altitude are baked from real astronomy for this latitude across the whole year — bud break, bloom, fruit-set, ripening and harvest are keyed to that real seasonal light, not a script.

What's real: the sky is baked from real astronomy — RiseSet.SunRiseSet + SolarPosition.GetHorizontal (OnlyCSharp.PhysicsAndAstronomy.Astronomy) computed daily for this exact latitude/longitude across all of 1999, plus the real bright-star field and Moon phase for the 1999-01-01 start. Every species is a real catalog row (name, origin, sweetness/energy, cold hardiness where cataloged) from OnlyCSharp.Data.Catalogs.Biology.Botany. The phenology STATE MACHINE is our own documented model layered on that real day length/sun-angle trend plus each species' real or estimated cold-hardiness zone — see orchard-engine.js's header for exactly which numbers are sourced vs. our own design. Four camera kits, a compass to swing the shadows, Fullscreen, and a Kiosk lock with slide-to-unlock.
