How it knows
Arrive by the start of golden hour with a few minutes to spare: the light is already warm, and the best colour, when it comes, arrives after the sun is down and lasts into blue hour. The colour outlook is the Oracle's call for that evening, made from the cloud forecast about two days ahead; before that the plan carries the geometry, which is exact. The link is the plan: whoever opens it sees this evening, this spot, this direction.
Where the sun goes down: face this way when you arrive.
The colour outlook — one of four words — arrives when the forecast reaches your evening, about two days before. The times are exact already.
The plan in your pocket, and a nudge when it's time to leave. Sol for iPhone is coming soon.
