/* Big-screen projection player for songs.
 *
 * A fullscreen overlay that shows one lyric line at a time (up to two tracks:
 * a top row and a bottom row), driven by the audio clock. The three themes
 * mirror the lineup presentation themes so a projected song reads as a sibling
 * of a projected lineup:
 *   [data-theme="default"] → Blue   (bb-slides.png background, white text)
 *   [data-theme="nb"]      → White  (#f8f9fa background, dark text)
 *   [data-theme="nb_logo"] → White + language wordmark watermark
 * (tokens taken from presentation.js.css / presentation.nb.js.css /
 *  presentation.logo.js.css).
