  Features:
  Automatic subtitle detection for Thai and Lao captions
  Real-time romanization (transliteration to Latin script)
  English translations shown alongside original lyrics
  Draggable overlay positioned right on the video player
  Toggle between Thai and Lao meaning sources
  Works on any YouTube video with Thai or Lao closed captions
  Minimal, non-intrusive dark-themed UI
  
  How It Works:
  Navigate to a YouTube video with Thai or Lao captions
  LyricLens automatically detects the language and fetches caption data
  As the video plays, the overlay shows the current lyric line with romanization and translation
  Click the extension icon to see status, detected language, and toggle settings
  
  Supported Languages:
  Thai (TH) -- full transliteration and English translation
  Lao (LO) -- full transliteration and English translation
  
  Privacy:
