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;
  }
}

```

`grid-column: span 4` is the bug. You’ve only got 3 explicit columns, so each `.card` is trying to span past the grid and the browser may create an implicit 4th track or do odd auto-placement stuff.

Fix it by spanning the full row instead of a magic number:

```auto
.card { grid-column: 1 / -1; }

```
