   Loaded by public/blog/index.html only, after blog.css. Kept out of
   blog.css on purpose: that file is shared by every article, the English
   blog and the tools pages, and generic names like .grid, .tool and .bar
   would leak into all of them.

   The layout: one photo grid, newest first, with the four semester stages
   as tabs in a toolbar that floats under the top bar next to the search.
   While nothing is filtered the newest guide is shown bigger, in whichever
   shape keeps every row full (see .grid[data-lead] below).

   Hebrew: no letter-spacing anywhere below -- tracking pulls Hebrew letters
   apart instead of opening the word up the way it does for Latin caps.
