This project reimplements the liveness detection model from Glance
(https://github.com/jonnyoo/glance) by Jonathan Zhou, MIT licensed.

The five-cue deny/confirm design, the tuning constants, and the reasoning
recorded in the comments of src/glanced/liveness/ originate there. The Swift
implementation was not copied; each module was rewritten against MediaPipe,
OpenCV and NumPy, and the deviations are documented at each site.

The ArcFace recognition model is from InsightFace
(https://github.com/deepinsight/insightface).

The lock screen's success animation (patches/omarchy-lock-faceid/
unlock-spin.png) is frames 16-45 of the unlock video shipped with Glance
(Resources/unlockanimation.mp4), cut to the inside of its ring and reduced
to an alpha mask so it can take the current theme's colour.
