pop/bin/lyricline.mjs ports imab's lyricline: the vocal stem over a bare click and kick placed on the chart's REAL beat times (not a fixed BPM), each word flashing at the instant its audio lands, a bar.beat counter in playing order, rendered for one window (--from/--to). SCORE.md gains "Tracking a vocal — the definitive process": seed, ear, collect + study, apply, prove. sailor-song v20k: "lately" on 28.2 — bar 27 plays out, one pickup beat, and the held "me" runs to that edge.
