/* ============================================================================
 * AlterSmoke — Checkout V2 · Lot 2 · deported step CTA in the sidebar
 * ----------------------------------------------------------------------------
 * Reference: Claude Design "Checkout AlterSmoke V2" (shell.jsx Sidebar
 * `.ck-loyal__cta`, app-v2.jsx `sidebarFire()`). One large sticky button inside
 * the order summary; its label follows the current step ("Continuer" on steps
 * 1-3, "Payer {total}" + lock on payment) and it proxies the step's native
 * action button (wired in alter-checkout-cta.js).
 *
 * Brand tokens only (Brockmann --as-font-family, amaranth --as-amaranth) — NOT
 * the maquette's DM Sans / approximate red.
 *
 * Desktop only: on <992px the wrap is hidden and the native buttons + the
 * existing mobile sticky total take over (no fight with the small layout).
 * ========================================================================== */
