/* Zero Sirup Mix & Match box: flavour gate + progress + store-style cards. Paste into Easy Bundles > Settings > Mix & Match > System > Custom JS. Skin: sections/main-mix-box.liquid puts the nine store cards (card-product.liquid) and the hero into window.__MIXBOX; this script shows them in place of the app's own cards and forwards (+) / (-) to the app's hidden buttons. Rule: 6-9 bottles need 2 different products, 10-15 need 3, 16 needs 4; max 16; no repricing, a bad box is refused. Hooks: gbbSdk.override('sdk'), cart.f.validateBeforeAdd, gbbSdkHelpers.utility.executeAddToCart, cart.f.getItems. Fail safe: add-to-cart stays blocked until the self test passes (window.__mixboxGate = pending|ready|failed); the theme section main-mix-box.liquid has a watchdog for the case that this script never runs. Storefront gate only, not a security boundary (needs a Shopify Function, i.e. Plus, for that). */ (function () { 'use strict'; var LOG = '[mixbox]'; var BLOCK_SELECTOR = '.gbbFooterNextButton, .gbbFooterNextButton *'; var state = { gate: 'pending', inst: null }; window.__mixboxGate = 'pending'; /* ---------- text (DE primary, EN translation) ---------- */ var T = { de: { flavour1: 'Sorte', flavourN: 'Sorten', q0: 'Wähle 6 bis 16 Produkte.
