   X = diameter of the dot above the "i"; symbol 0.5D where D = circle diameter.
   Measured from the approved master raster: the dot is 5.9% of the wordmark's
   inked width, and the master file carries 10.2% transparent padding at the
   inline edges — so the supplied asset already satisfies 1X at any size.
