       a pricing table that changes to two columns and still shows feature + all tiers is hard.
       A simpler approach for mobile would be to show feature + ONE tier at a time, or stack the tiers vertically.
       Let's assume the pricing table must maintain its feature comparison nature.
       For strict column count, I will use `grid-template-columns: 1fr` and allow vertical stacking on mobile. */
