 ## Notes
 
 - The project targets Wear OS API 33+, which makes it suitable for the Pixel Watch 1.

+- The blue lights flash intentionally instead of staying lit. The logic lives directly in `watchface.xml`; the off/hourly/always behavior is a WFF `ListConfiguration` user setting. Note that "Always on" costs noticeably more battery while the display is active.
 - The geometry is built entirely from WFF vector primitives; the watch face itself has no bitmap dependency.
