{{-- Standalone preview page for the VS intro overlay. Renders the same
partial that appears over the match player, in a fixed 16:9 stage
centered on a blank page, with no video element behind it. --}}
VS Preview — {{ $video->title }}
{{-- The partial's script pauses/plays #videoPlayer to hold playback
until the countdown ends. On the preview page there is no source
to play, but the countdown itself is real-time so the overlay
still ticks 5 → 0 and dismisses correctly. --}}
