   tiles; Feed / Labs / Diary are one big tile each in a row below. Cells are
   squares sized from the container width (cqw), so every span stays square
   and both grids share the same cell system. js/home-grid.js assigns each
   work tile its span through custom properties: --c (columns), --r (rows),
   --cs (forced start column).
