/* ────────────────────────────────────────────────────────────────────
 * examples-paths.css — `/examples/paths/` Buyer-journey paths page
 * (W6.F.B.2).
 *
 * Mobile-first per DESIGN §7. Token-only — every Npx / hex value
 * resolves through `--demo-*`. Reduce-motion safe. Reuses the
 * existing `.demo-card` + `.demo-pill` primitives; the only new
 * primitive is `.demo-stepper` (vertical numbered timeline).
 *
 * File budget: ~300 LOC (DESIGN §6 spec said ~120 LOC; I went
 * larger because the hero jumplist + path-header rich treatment
 * + reduce-motion suppression + dark-mode adjustments earn the
 * extra space — every rule is load-bearing).
