Reference lines:
- Kept per metric (dict keyed by metric_id) so switching metrics and coming back
preserves them, instead of clearing on every switch
- Spectrogram lines read/edit/drag in Hz: the renderer installs Hz<->row-index
transforms (the heatmap y-axis is a row index), so value, label, the edit
dialog, and the new-line default all speak frequency. Curve metrics stay
identity. Round-trip verified (1000 Hz -> row -> 1000 Hz)
- Line label and drag-readback always in the metric's natural units
Controls:
- Relative-time abs/rel is now a checkbox toggle, not a dropdown
- Removed the font control panel; UI font is locked to M PLUS 1 Code @ 10pt via
font_manager.apply_fixed_font (system-default fallback). Deleted
font_control_widget.py

Reference lines:
- Side-panel cluster (ref_line_widget.py): list of lines with Add/Edit/Remove/
Clear and a properties dialog (value, colour, line style, tag)
- Lines own their state as RefLineProps (held by MainWindow), drawn with a
triangle drag-handle; dragging writes the value back and refreshes the list
- Replaces the old centre-only add-and-drag-the-whole-line approach
Comparison:
- Time-axis mode selector: Absolute (seconds) vs Relative (% of each track's own
length), so a long track and a short one line up by song position. Pure view
transform (plotspec.apply_x_mode), no recompute
- Overlaid different-length tracks now autorange their x union in absolute mode
instead of clipping to the first track's span
