/* Beau Bottles — Kaching Cart "Build a Bundle" promo + handoff. Requires a Custom HTML module: + the .bbp CSS. Counts wrap UNITS, shows the correct "X more", and links to the Bundle Builder preloaded via ?seed= with ONE seed entry per unit (qty preserved). The cart is left fully intact on handoff — de-duping happens only at bundle commit (in the builder's checkout), so a shopper who peeks never loses items. */ (function () { var WRAP_TYPE = 'Bottle Wrap'; var BUILDER = '/pages/build-a-bundle'; var MOUNT_ID = 'bb-bundle-promo'; function freeFor(n) { if (n >= 15) return 8 + Math.floor((n - 15) / 5) * 2; if (n >= 10) return 4; if (n >= 5) return 1; return 0; } function nextTier(n) { var t = [5, 10, 15]; for (var i = 0; i < 3; i++) { if (n < t[i]) return t[i]; } var nx = Math.ceil((n + 1) / 5) * 5; return nx <= 30 ? nx : null; } function packFor(n) { if (n <= 5) return 5; if (n <= 10) return 10; if (n <= 15) return 15; return Math.min(30, Math.ceil(n / 5) * 5); } var lastSig = null; function render(cart) { var mount = document.getElementById(MOUNT_ID); if (!mount) return; var wraps = (cart.items || []).filter(function (i) { return i.product_type === WRAP_TYPE; }); var count = wraps.reduce(function (a, i) { return a + i.quantity; }, 0); // wrap UNITS, not line count var handles = []; wraps.forEach(function (i) { if (handles.indexOf(i.handle) < 0) handles.push(i.handle); }); // unique designs (signature) var seed = []; wraps.forEach(function (i) { for (var q = 0; q < i.quantity; q++) seed.push(i.handle); }); // ONE entry PER UNIT -> preserves qty var sig = count + '|' + handles.join(','); if (sig === lastSig && mount.querySelector('.bbp')) return; // unchanged + intact -> skip (avoids observer loop) lastSig = sig; var got = freeFor(count), nt = nextTier(count), need = nt ?
