Design Blueprint: Motion Light Height

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24121657): A motion-activated light protects only the ground its sensor actually sees, and mounting height moves two boundaries at once: the far edge of detection, set by the sensor's 12 m slant range, and the dead zone beneath the fitting, which grows with height. This study samples a 5 m by 8 m driveway on a 0.1 m grid from stated assumptions, testing each point against the range limit and a dead zone whose radius is 0.45 times the mounting height. Coverage is highest at the lowest tabulated height and falls as the dead zone swallows the near corner: 97.5 percent at 2.5 m against 90.2 percent at 5 m, w Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
