/*
 * Ported from docs/checkout-project/prototypes/v1-wizard.html.
 *
 * One thing was deliberately left out of the port, per the V1 plan:
 *   - The .screen/.visible JS-driven display toggle: in Rails each wizard
 *     step is a full page, so a screen just renders (kept the .screen
 *     entrance animation, dropped the show/hide rule).
 *
 * The #dock mobile bottom-drawer (stepper/basket reparented by the dock
 * Stimulus controller into a fixed footer with a proxied CTA) is ported
 * below, alongside the responsive .layout rule it replaces at ≤880px.
