/* Optional CSS Enhancement

You might want to add some styling to make the footer text look better. Add this to your `common.css`:
```css
.footer-bottom p {
    margin: 0.25rem 0;
    line-height: 1.4;
}

.footer-bottom p:first-child {
    font-weight: 500;
}

.footer-bottom p:last-child {
    font-size: 0.9rem;
    opacity: 0.9;
}
```
