AsyncPicPalette

A data class returned via onPaletteLoaded containing extracted color swatches from the loaded image.

    val vibrant: Color?,
    val dominant: Color?,
    val muted: Color?,
    val lightVibrant: Color?,
    val darkVibrant: Color?

    modifier = Modifier.size(200.dp),
    onPaletteLoaded = { palette ->
        // Safely unwrap — any swatch may be null
        val accent = palette.vibrant ?: palette.dominant ?: Color.Gray
        val bg = palette.darkVibrant ?: Color(0xFF1E293B)
    }
)

Internal Use

AsyncPic uses AsyncPicPalette internally to drive the Adaptive Shimmer Morph feature. Before calling onPaletteLoaded, it updates the shimmer's activeShimmerColor with this priority:

1. vibrantSwatch
2. lightVibrantSwatch
3. dominantSwatch

This means even if you don't pass onPaletteLoaded, you still get the color morphing effect automatically.
