## Use MeshGradient for Premium Dynamic Backgrounds

What separates a premium `MeshGradient` from a gaudy one is the same thing that separates good lighting from a neon sign. Colors should blend through neutral midpoints rather than creating muddy intermediate hues, and the gradient should feel like light falling across a surface, not a candy-colored blob. When done well — as Apple demonstrates in Weather — a mesh gradient adds depth and warmth that a flat two-stop `LinearGradient` simply cannot achieve, communicating quality before the user reads a single word.

**Incorrect (flat LinearGradient for a hero surface):**

```swift
struct PaywallHeader: View {
    var body: some View {
        VStack(spacing: 16) {
            Image(systemName: "crown.fill")
                .font(.system(size: 48))
            Text("Upgrade to Pro")
                .font(.largeTitle.bold())
        }
        .frame(maxWidth: .infinity, minHeight: 300)
        .background(
            LinearGradient(
                colors: [.blue, .purple],
                startPoint: .topLeading,
                endPoint: .bottomTrailing
            )
        )
    }
}
```

**Correct (MeshGradient with control points for organic color flow):**

```swift
struct PaywallHeader: View {
    var body: some View {
        VStack(spacing: 16) {
            Image(systemName: "crown.fill")
                .font(.system(size: 48))
            Text("Upgrade to Pro")
                .font(.largeTitle.bold())
        }
        .frame(maxWidth: .infinity, minHeight: 300)
        .background(
            MeshGradient(
                width: 3,
                height: 3,
                points: [
                    [0.0, 0.0], [0.5, 0.0], [1.0, 0.0],
                    [0.0, 0.5], [0.5, 0.5], [1.0, 0.5],
                    [0.0, 1.0], [0.5, 1.0], [1.0, 1.0]
                ],
                colors: [
                    .indigo, .blue, .purple,
                    .blue, .cyan, .indigo,
                    .purple, .indigo, .blue
                ]
            )
        )
    }
}
```

**Exceptional (the creative leap) — a gradient with a focal point like a painting:**

```swift
struct PremiumHeader: View {
    var body: some View {
        VStack(spacing: 16) {
            Image(systemName: "crown.fill")
                .font(.system(size: 48))
                .foregroundStyle(.white)
            Text("Upgrade to Pro")
                .font(.largeTitle.bold())
                .foregroundStyle(.white)
        }
        .frame(maxWidth: .infinity, minHeight: 300)
        .background(
            MeshGradient(
                width: 3,
                height: 3,
                points: [
                    [0.0, 0.0], [0.5, 0.0], [1.0, 0.0],
                    [0.0, 0.5], [0.55, 0.42], [1.0, 0.5],
                    [0.0, 1.0], [0.5, 1.0], [1.0, 1.0]
                ],
                colors: [
                    Color(red: 0.15, green: 0.10, blue: 0.30),
                    Color(red: 0.20, green: 0.12, blue: 0.35),
                    Color(red: 0.12, green: 0.08, blue: 0.28),

                    Color(red: 0.25, green: 0.14, blue: 0.40),
                    Color(red: 0.85, green: 0.55, blue: 0.30),  // warm focal point
                    Color(red: 0.18, green: 0.10, blue: 0.32),

                    Color(red: 0.10, green: 0.08, blue: 0.22),
                    Color(red: 0.14, green: 0.10, blue: 0.28),
                    Color(red: 0.08, green: 0.06, blue: 0.20)
                ]
            )
        )
    }
}
```

The secret is that one control point -- the center, nudged slightly up-left -- carries a warm amber while everything around it cools to deep indigo. This creates a focal point the way a Renaissance painter places a candle in a dark room: your eye is drawn to the warmth, and the crown icon sits right in that glow. The surrounding colors are close relatives (deep purples and navy), so transitions never pass through muddy browns. The gradient doesn't compete with the content -- it cradles it.

`MeshGradient` requires iOS 18+. Provide a `LinearGradient` fallback for iOS 26 deployments:

```swift
.background {
    if #available(iOS 18.0, *) {
        MeshGradient(width: 3, height: 3, points: /* ... */, colors: /* ... */)
    } else {
        LinearGradient(colors: [.indigo, .purple], startPoint: .topLeading, endPoint: .bottomTrailing)
    }
}
```

Limit `MeshGradient` to one per screen — multiple mesh gradients competing for attention dilute the premium effect. Animate control points with `TimelineView` for a living, breathing background on splash or paywall screens.

**When NOT to apply:** Utility screens (settings, forms, lists) where a solid or system background is appropriate, and any screen that must support iOS 26 without a degraded fallback experience. Limit to one mesh gradient per screen.
