"""
Canonical UI geometry contract for the live Bluestacks pipeline.

Everything here is expressed in *normalized coordinates inside the game viewport*
(after black bars/padding are removed):
  x_n in [0,1], y_n in [0,1]

This keeps the extractor/executor stable across resolutions and window borders.
