Summary of Changes

Hello @pedrosax, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the developer experience for HomeScreen.kt by improving its Compose Preview capabilities. It introduces logic to display static placeholder images for dynamic content like dancing bots and video players when the UI is rendered in a preview environment, ensuring that the layout is visually complete and representative without relying on live data or complex player initialization.

Highlights

• Compose Preview Enhancements: Implemented conditional rendering for the DancingBot and VideoPlayer composables to display static placeholder images when the UI is rendered in Compose Preview mode.
• Improved Developer Experience: Replaced previously blank or non-functional preview elements with meaningful visual placeholders, making the HomeScreen.kt previews more representative and useful for design-time inspection.

Code Review

The code changes introduce placeholders for Compose Preview for HomeScreen.kt, which enhances the preview experience by using static images when in inspection mode. This avoids issues with dynamic content loading during design time.

Consider extracting the Image composable into a separate function for better readability and maintainability. This would encapsulate the placeholder logic and make the VideoPlayer function cleaner.

@Composable
private fun VideoPlaceholder(modifier: Modifier = Modifier) {
    Image(
        painter = painterResource(id = R.drawable.promo_video_placeholder),
        contentDescription = null,
        contentScale = ContentScale.Crop,
        modifier = modifier,
    )
}

// Usage in VideoPlayer:
if (LocalInspectionMode.current) {
    VideoPlaceholder(modifier = modifier)
    return
}

        contentDescription = null,
