## Customization Tips

### Changing Primary Brand Color

Replace `--ctp-mauve` throughout with another accent:
```css
/* Example: Use blue as primary */
.hero-title {
    background: linear-gradient(135deg, var(--ctp-blue) 0%, var(--ctp-sapphire) 100%);
}

.link-button:hover {
    border-color: var(--ctp-blue);
}
```

### Adjusting Transparency

More opaque terminal:
```css
theme: {
    background: "rgba(48, 52, 70, 0.9)", /* Change from 0.75 */
}
```

Less blur:
```css
backdrop-filter: blur(10px); /* Change from 20px */
```

### Custom Button Colors

Add a new button style:
```css
.link-button.custom {
    border-color: rgba(133, 193, 220, 0.3);
}

.link-button.custom:hover {
    border-color: var(--ctp-sapphire);
    box-shadow: 0 8px 24px rgba(133, 193, 220, 0.25);
