/**
 * Variant CSS: process--node-stepper-horizontal
 *
 * Process steps as a horizontal progress-stepper UI: small FILLED accent badge
 * circles sit on a shared rail, with a connector segment drawn between adjacent
 * nodes (each node draws the segment to its successor via ::after). Title +
 * description sit centered below each badge. Reads like a "step-by-step" wizard.
 * Distinct from horizontal-connector-nodes (outlined ring circles + one
 * edge-to-edge line) and numbered-steps-row (big numerals on a chip). Filled
 * badge uses --cta-text-primary on --accent so the digit stays legible in every
 * theme (no --bg-main-as-foreground, KI-020). Every selector scoped to the
 * variant (no global leak). Part of the `process` role.
