/**
 * Variant CSS: benefits--center-spine-alternating
 * Layer 2 — Path B benefits role (2026-06-06).
 * Two-sided timeline: a single vertical line runs down the center of the
 * section; benefit cards sit alternately to its left and right, each pinned to
 * the spine by a node dot. Distinct from the single-column timeline-spine.
 * Text stays --ink (polarity-aware); spine + dots use color-mix on accent/ink.
 * Every selector scoped to .universal-benefits--center-spine-alternating.
