The header is already blue, so the app-icon-in-a-white-pill looked like blue→white→blue→white
nesting. Use a transparent mark (mark-light.svg: white C + gold dot) placed directly on the blue
header (home/index/connect/dashboard), dropping the white background + padding. share.html keeps
the full app icon (it's a light card, not the blue bar).
