Grid Garden

Fun game. One thing I dislike about the grid system is how the range is defined as [start,finish). This probably comes from some lower-level implementation detail, but it would be far more ergonomic if the range included the end value. Typing `grid-column: 2 / 6` when there are only 5 columns just looks like a bug.
