Thank you Hans, this was the approach I needed. After adding some padding to the top, a blank line to the title, and repositioning the callout to Above, I received exactly the plot desired. :)
PlotRangePadding -> {{0., 0.}, {0., 0.05}},
Richard, should not the tick marks be swapped?
Hah! Good catch. I likely misordered them in FrameTicks.
