/* Grid and flex items default to `min-width: auto`, so an item containing wide
   intrinsic content (a 520px table, a long unbroken string) expands its track
   and pushes the whole page wider than the viewport. Because `body` sets
   `overflow-x: hidden`, that content then becomes unreachable rather than
   scrollable. Zeroing the automatic minimum keeps columns at their track size
   and lets `.table-wrap` scroll internally instead. */
