The notes box now routes each line to a target: 'seg2: fast' (by number, also '2:'
/ 'S2:'), '10s-15s: drop' (by time range / '12.3s:'), or unprefixed = global. Segment
notes are attached to the matching segment in the summary (marked NOTE, overrides the
energy default) and drawn on the waveform image; time notes attach to overlapping
segments (strict end boundary); globals listed separately. README documents the syntax.
