libs/score_view carries the engraving, spacing, font and document code out of the score app so any app can show notation: a ScoreView widget with width/page/content fits, pan and zoom, a playhead, a dark palette, drum-key labels, lyrics under melody notes, and builders for drum, pitched and bass-tab scores. The score app uses it. Vector glyphs no longer write depth for transparent fragments, and the Metal screenshot staging sizes itself from the source texture.
