// macclick — post synthetic mouse events to the focused app at global
// (display-point, top-left-origin) coordinates. Used to drive the *real*
// running mnml in its ghostty window (paired with scripts/shot.sh to see the
// result). No dependencies beyond the system Swift toolchain.
//
// Coordinates are display POINTS, not retina pixels, and share the same space
// as `System Events` window position and `screencapture -R`. To turn a spot in
// a shot.sh PNG into a click point: pt = window_origin + (pixel / backing_scale).
//
// Usage:
//   macclick move  X Y
//   macclick click X Y            # left single
//   macclick rclick X Y           # right single
//   macclick dblclick X Y         # left double
//   macclick scroll X Y DELTA     # wheel at X,Y (DELTA>0 scrolls up)
