- Per-track start/end points (mm:ss inputs, 'set to current' buttons, draggable handles on the waveform). Trim applied via audio.setTrim (seek to start, stop at end) and pushed live to the playing track. - Wider cards showing elapsed / total / remaining for the trimmed range. - Waveform rendered per track: peaks computed in main via ffmpeg (mono 8kHz PCM -> 400 normalized buckets, cached), drawn on a canvas with trim region + playhead. New audio:peaks IPC + djv.peaks preload binding. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
