/**
 * Variant CSS: process--roadmap-horizontal-band
 * Layer 2 — Path B process role (2026-06-06).
 * A horizontal roadmap on a DARK band: milestones spread along one connector line,
 * each marked by a dot, with labels alternating ABOVE (.--up) and BELOW (.--down)
 * the line. The line is a pseudo-element on the track; each node owns its dot.
 * Distinct from vertical-timeline (vertical) and node-stepper-horizontal (light).
 * Dark surface → text uses var(--text-on-dark); accent stays visible via the lift
 * mix so we never hit the dark-on-dark / bg-main-as-fg trap (KI-020).
 * Every selector scoped to .universal-process--roadmap-horizontal-band.
