   `table { display: block; overflow-x: auto }` does NOT achieve this (the table's
   internal layout still gets constrained to the block box's width, so columns
   squeeze instead of overflowing) — an actual wrapper element is required so the
   table can lay out at its natural width and the wrapper scrolls. See the
   `wrapResultTablesForScroll` MutationObserver in app.js, which wraps every
   .result-table in a .table-scroll div as it's added to the DOM. */
