Video Thumbnail

VideoThumbnail is the default UI for rendering video thumbnails in MessageList.

Best Practices

• Provide a fallback thumbnail when thumb_url is missing.
• Keep thumbnail sizes consistent with image galleries.
• Avoid heavy overlays that obscure the preview.
• Ensure tap targets are clear for play/open actions.
• Use cached images for smooth scrolling performance.
