Layout bug is hidden in plain sight.

```css
.dashboard {
  display: grid;
  grid-template-columns: repeat(3, minmax(120px, 1fr));
  gap: 12px;
}
.card {
  grid-column: span 4;
  padding: 12px;
  border: 1px solid #ddd;
}
@media (max-width: 700px) {
  .dashboard {
    grid-template-columns: 1fr;
  }
}

```

That `grid-column: span 4; ` on `. card` is busted, because your grid only defines 3 columns. In CSS Grid, spanning past the explicit columns makes the item create an implicit extra column, so you get weird overflow/spacing like your layout is “making a 4th lane” nobody asked for. Fix is just to span what exists (or don’t span at all if every card is the same size):

```auto
.card { grid-column: span 3; } /* or just remove grid-column */
@media (max-width: 700px) { .card { grid-column: 1 / -1; } }

```
