/*
 * TWO READINGS ON ONE AXIS. Each arm is a head line — the label and its figure
 * at either end — over a full-width track, so both tracks start and end on the
 * same two x's whatever the labels measure.
 *
 * The SUBJECT's fill is the screen's accent and the reference's is neutral: one
 * hue, and the grey says what is being measured against.
