/* The one media player (templates/techniques/_player.html, js/media-player.js): podcast episodes, "real English" clips and
   the learner's own files. Apple Podcasts / Music "Now Playing": one card with the practice modes on top, square artwork
   (generated from the show's slug when there is no poster) or the video, title and show, a scrubber with played and
   buffered tracks and a knob that grows on press, back 15 / play / forward 30, then speed, sentence repeat and previous /
   next sentence. Desktop: the card is sticky beside an Apple-style transcript; phones: one column, and a mini player docks
   above the tab bar once the card scrolls away. Site tokens only (app.css), so light/dark follow; logical properties; the
   timeline and transport are LTR (media controls follow time, not reading). Per-frame motion is transform/opacity only:
   JS writes the unitless --p (0..1) and the knob uses container units, so playback never triggers layout. */
