 * Billing grid breakpoints — keyed to content area width, not viewport.
 * Desktop sidebar ≈ 240px + ~96px padding = ~336px overhead.
 * Tablet sidebar  ≈ 200px + ~56px padding = ~256px overhead.
 * Mobile (≤640px): full width with ~32px padding, no sidebar.
 *
 * At ≤1050px viewport the content area is too narrow for 4 comfortable columns → 2×2.
 * At ≤640px mobile layout kicks in → full width, keep 2 columns.
 * At ≤460px cards are too narrow even at 2 columns → single column.
