PNG LOGOS

Use these when an app will not accept SVG. Each logo is 3000 pixels wide
(the number in the file name) — big enough for print, and far bigger than a
slide or an email signature needs. Place it and shrink it to fit. Shrinking
is fine; enlarging makes the edges soft.

Both have transparent backgrounds, so they sit on whatever is behind them.

As with the SVGs: the white logo (for dark backgrounds) looks blank in a file
browser preview. It is there — it is white on the preview's white.
