Bothy The Route
A hill route on a map with no tiles and no photograph, where the contours are nested rings computed per level, the loop is a measured spline cut at kilometres so the seven waypoints sit at their true distance, each stretch is drawn in the colour of what is underfoot, and the scale bar is read back out of the drawing.

The rule this design follows
It ships exactly as previewed: same colors, same type, same copy, same motion. The prompt tells your agent to build that, and not to adapt it to your existing theme.
