Legend Combo

Gallery / Feature Showcase

Demonstrates `%%metro legend_combo:`: a normal (blue) and tumor (red) line travel together as a tumor-normal pair. The combo renders one legend row with a striped red+blue swatch. Normal travels only within the bundle so its individual row is suppressed, while tumor breaks away alone to Annotate and keeps its own row; the QC line is unaffected.
