"VecNet" title too bold on Macs

[DanielBaird]

Macs render light-text-on-dark way fatter than it should be. This shows up in the white title on red. The attached screenshot shows Windows rendering on the left, OSX rendering on the right.

The fix is to add these CSS lines to the light text section:

    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
