/* Dividers: a true bordered table-grid, not a one-off line per item.
   Technique: the grid container gets a top + left border, and every item
   gets a right + bottom border with padding equal to the normal grid
   gutter. Because each shared edge is only ever drawn once (container
   draws the outer top/left, each cell draws its own right/bottom), the
   result is a clean, evenly-spaced bordered grid with no doubled-up
   corners, no gap math, and no last-row/last-col edge cases to special
   case — it works identically for any column count or ragged final row. */
