Keycard styles

Style key card components with custom gradients, logos, corner radius, and shadows.

Controls the look of key card UI (background gradient, logo, shadow, corner radius, etc.).

public struct KeyCard {
    public var backgroundGradient: [Color]
    public var accentColor: Color
    public var logoAssetName: String
    public var cornerRadius: CGFloat
    public var shadowColor: Color
    public var shadowRadius: CGFloat
    public var shadowYOffset: CGFloat
}

Examples:

// Change only the corner radius (uses builder).
let rounded = SeamTheme.KeyCard.default.with(cornerRadius: 24)

// Full control via initializer.
let branded = SeamTheme.KeyCard(
    backgroundGradient: [.blue, .purple],
    accentColor: .white,
    logoAssetName: "MyBrandLogo",
    cornerRadius: 18,
    shadowColor: .black.opacity(0.12),
    shadowRadius: 12,
    shadowYOffset: 6
)
