## ACCESSIBILITY REQUIREMENTS

### Color Contrast

**Must meet WCAG AA (4.5:1 for normal text, 3:1 for large text)**

| Combination | Ratio | Status |
|------------|-------|--------|
| Gold (#C4A24E) on Dark (#0d0d0f) | ~5.2:1 | ✅ |
| Steel (#7B8794) on Dark (#0d0d0f) | ~4.5:1 | ✅ |
| Amber (#E07A2F) on Dark (#0d0d0f) | ~6.8:1 | ✅ |
| Light Text (#e0e0e0) on Dark (#0d0d0f) | ~16:1 | ✅ |

### Focus States

All interactive elements must have visible focus states:
```css
a:focus,
button:focus,
input:focus {
    outline: 2px solid #C4A24E;
    outline-offset: 2px;
}
```

### Touch Targets

- Minimum 44px × 44px for buttons, links
- Mobile links need generous padding
- Hover states clear on touch

---

## TRANSITION & ANIMATION GUIDELINES

**Standard Transitions**
```css
/* Quick feedback (UI elements) */
transition: all 0.2s ease;

/* Smoother, more natural (larger movements) */
transition: all 0.3s ease;
```

**Common Effects**
```css
/* Hover lift */
transform: translateY(-2px);

/* Card expand on hover */
transform: translateY(-4px);
box-shadow: 0 8px 24px rgba(0, 0, 0, 0.4);

/* Smooth color change */
color: #C4A24E;
transition: color 0.2s ease;
```

**Performance Notes**
- Use `transform` and `opacity` for smooth 60fps animations
- Avoid animating width/height (causes layout reflow)
- Keep animations under 300ms for snappiness
- Test on mobile devices for smooth performance

---

## GRADIENT USAGE

**Hero Title Gradient**
```css
background: linear-gradient(135deg, #C4A24E, #E07A2F);
-webkit-background-clip: text;
-webkit-text-fill-color: transparent;
background-clip: text;
```

**Header Background**
```css
background: linear-gradient(135deg, #0d0d0f 0%, rgba(0, 0, 0, 0.5) 100%);
```

**Hero Section Background**
```css
background: linear-gradient(135deg, rgba(196, 162, 78, 0.05) 0%, rgba(224, 122, 47, 0.05) 100%);
```

---

## TRANSPARENCY SCALE

Use rgba with consistent alpha values for hierarchy:

```css
/* Very subtle */
rgba(255, 255, 255, 0.02);    /* Cards, subtle bg */

/* Subtle */
rgba(255, 255, 255, 0.03);    /* Card containers */

/* Noticeable */
rgba(255, 255, 255, 0.05);    /* Card hover, slight emphasis */

/* Strong */
rgba(255, 255, 255, 0.08);    /* Form inputs, secondary bg */

/* Dark overlays */
rgba(0, 0, 0, 0.3);            /* Footer bg */
rgba(0, 0, 0, 0.5);            /* Header gradient end */
```

---

## BORDER RADIUS

```css
--radius-sm: 3px;      /* Code blocks, small elements */
--radius-md: 6px;      /* Buttons, inputs, cards */
--radius-lg: 8px;      /* Card containers, larger components */
--radius-xl: 12px;     /* Hero sections, large containers */
```

---

## BOX SHADOWS

```css
/* Subtle */
box-shadow: 0 2px 4px rgba(0, 0, 0, 0.2);

/* Medium (hover states) */
box-shadow: 0 4px 12px rgba(196, 162, 78, 0.3);

/* Strong (dropdown, modal) */
box-shadow: 0 8px 24px rgba(0, 0, 0, 0.5);
```
