// =========================================================================== // EGO CART (Opus) — App "Custom scripts" — v3 // // Paste this ENTIRE file into the ego-cart-upsell app's "Custom scripts" field. // // vs v1: adds FC Pre-order split / overflow status mirroring into the cart // drawer. SAFE-BY-DESIGN — on any theme WITHOUT the pre-order Liquid (i.e. the // current LIVE theme) the status map is empty and every new code path is a // no-op, so SEPA + free-shipping + in-stock behaviour is unchanged. The SEPA // delegate below is identical to v1. // // vs v2: adds the OPT-IN split-line reconciler (fcReconcileCart). When the theme // sets window.fcPreorderSplit AND its status nodes carry data-fc-split (double // gate — the LIVE theme sets window.fcPreorderTheme already, so the reconciler // must never key off that alone), ordering beyond available stock is kept as // TWO cart lines: a plain in-stock line and a pre-order line carrying the // hidden `_fc_preorder` property + a visible `Pre-order: ` // property (shows at checkout, on the order, and in notifications; Shopify Flow // tags the order off `_fc_preorder`). Without BOTH gates this file behaves // byte-for-byte like v2 (single line + order note attribute). // // v3.1: the reconciler runs ONLY at page load and checkout intent — never on // cart-change events. The Opus stepper writes absolute quantities from the // app's remembered state, so background mutations while the drawer can act // insert phantom units on the next click. The add itself is pre-split by the // theme's PDP interceptor (assets/fc-preorder-split-add.js), so the drawer's // own cart fetch already sees the final two-line layout with accurate steppers. // // v3.3: LIVE stepper re-split (fcInstallStepperRewrite). The drawer's + on an // in-stock line is rewritten IN FLIGHT (window.fetch patch on /cart/change| // /cart/update): the overflow goes onto the pre-order line and the plain line // stays capped at available stock — and the caller receives the FINAL cart as // the response to its own request, so its internal state is never stale (the // v3.0 corruption cannot recur: that came from mutating OUTSIDE the app's // request cycle). Requests we don't fully understand pass through untouched // and the load/checkout convergence remains the safety net. // =========================================================================== // SEPA checkout: robust, no dependency on a shadowRoot variable. // Delegates from document (capture phase) and survives re-renders.
