Match Blastware's layout, measured off the reference PDF: the sensor-check strip shares a border with the main waveform panel (no gap between them), and the per-lane "0.0" baseline labels sit to the RIGHT of the strip. Previously the strip floated with a gap and the "0.0" label overprinted the strip's left edge. Purely layout — the traces and decode are unchanged.
