/**
 * Variant CSS: stats--growth-timeline
 * Layer 2 — Path B stats role (2026-06-06).
 * Key numbers along a horizontal timeline: year above a dot on a connector
 * line, big metric + label below. Static (no JS). Distinct from
 * metric-counters-row (vertical dividers) via the running timeline rail.
 * EVERY selector scoped to .universal-stats--growth-timeline (no global leak).
