// packages/components/src/production/video_player.rs
// Video player component

// Platform API: Uses tairitsu WIT bindings for video playback control
// (play, pause, seek, mute, volume) via html-media-element interface.
// Stubs are provided in platform/wit.rs for environments without WIT support.
