Function pin_label_anchors 

pub fn pin_label_anchors(pos: Pos2) -> (Pos2, Pos2)

The two draw anchors for a pin’s labels, both vertically centered: the name on pos (the pin’s stub), and the type one [GRID_SIZE] below — nudged up by [TYPE_SHIM_Y]. Content-independent, so the render, placeholder, and hit-test paths place both lines identically. Returns (name_pos, type_pos).
