 Public `Option`, `Config`, `QualityLevel`, `AudioTrack` and `Result` types are exported from the root entry. The root and legacy import paths remain available. The types do not pretend every ArtPlayer instance already owns an Hls.js engine; describe `art.hls` in your application's integration types.
 
+The registered result contains only the fixed `name: 'artplayerPluginHlsControl'` and `update()`. Ordinary factory calls may omit the options, while the last declaration overload keeps its parameter required: `Parameters<typeof hlsControl>[0]` remains `Option`, without `undefined`.

 ## Validation scope
 
 The refactor tests Hls.js 1.5.17 and 1.7.2 with local media and real workers; these are tested points, not a newly declared supported range. Firefox grouped-stream crashes and a separate switching stall remain under investigation. Windows Playwright WebKit lacks the MSE path used in those tests; it does not establish Safari/iOS native-HLS acceptance. Verify your actual streams and target devices before adopting the unpublished refactor.
