// DayGlowView.swift — a non-interactive inner radial glow that frames the
// window in the focused day's color, the way the deskflow fullscreen
// highlight hugs the screen edges. Clear through the center (content stays
// readable), the day color easing in toward the borders. Sits on top of
// everything but passes all clicks straight through.
