Northern twin test page
The Polaris Perpetual
A northern-sky clock-calendar where Polaris is the pivot, the Big Dipper pointers become the hand, and one familiar sky movement reads both hour and season.

Testing area
Hard-coded sponsor placeholder view.
The clean review copy above removes the sponsor claim. This separate test lane keeps the original placeholder visible so we can judge the wording, placement and visual weight before deciding whether it belongs.
Atomic summary
One sky object, one readable promise.
CalculationTime should present this like a precision instrument, not a pile of cards. The page gives the sponsor or reviewer the product first, then the proof: what moves, what it means, and why it belongs here.
