  "sourcesContent": ["/* EG REWARD LINES - the drawer script of snippets/eg-reward-cart.liquid (RFC 0007 S70).\n *\n * WHAT IT DOES. It marks the UpCart drawer row of every one-time EG reward line - a cart line that\n * carries the property the snippet names, _Gifted, and is on no selling plan - with the attribute\n * data-eg-reward, and the snippet's style then hides that row's \"Upgrade to Subscribe & Save\"\n * section and any select in it. Every other row is left exactly as UpCart drew it, and so is a\n * reward line that is already on a plan: it has lost its reward already, and its plan select is the\n * drawer's only sign that it renews and its only way back to one-time purchase. It never writes to\n * the cart: its only request is a GET of cart.js.\n *\n * WHY A CACHED ASSET, NOT INLINE. Its code is about 4 KB once the comments are stripped (as Shopify's\n * CDN serves theme JS; under 2 KB compressed), the same on every page, so as a file it is downloaded\n * once and cached across pages, while an inline script is sent again with every page's HTML, comments\n * included (inline scripts are not minified). That is not tiny next to the inline precedent,\n * snippets/hide-internal-cart-properties.liquid (under 1 KB). Deferred is early enough: it runs before\n * UpCart's own bundle, and no flash needs preventing. If the file fails to load, nothing is hidden,\n * which is exactly the state before this fix. The snippet keeps the 150-byte style inline (a\n * stylesheet would cost a request on every page for nothing). The same split as assets/bfcm-sub-cart.js\n * (PR 3b, RFC 0007 S57), six-pack-cart.js and loop-plan-guard.js.\n *\n * ITS DATA. The loader tag carries three attributes, all from Liquid: data-eg-reward-prop (the\n * property name), data-eg-reward-lines (every line key of the cart the page was rendered with) and\n * data-eg-reward-gifted (the keys among them of one-time reward lines: the rows to mark). Shopify\n * builds a line key from the variant id and a hash of the line's properties and selling plan (a plan\n * change gives the line a new key, as assets/six-pack-cart.js notes), so a key never changes what it\n * names: once seen, it is known for good. Nothing in this file is Liquid.\n *\n * WHEN IT READS THE CART. Never while the drawer has no rows. Otherwise only when the drawer's row\n * signature (each row's id and quantity, as assets/bfcm-sub-cart.js and six-pack-cart.js sign it) has\n * changed AND a row holds a line key this page does not know yet: a line added after the page was\n * rendered. DEBOUNCE ms after the last such change, one read at a time; a change that lands during a\n * read gets one more read afterwards, and only if a row is still unknown then. When the rows go away\n * (UpCart draws none while its drawer is closed) the signature is cleared, so the same rows drawn\n * again count as a change: a read whose timer fired while no row was there is not lost. A read that\n * has not answered after READ_LIMIT ms is given up: aborted, its answer unused, the lock released.\n * A failed, unreadable or given-up answer changes nothing - every row keeps what UpCart drew - and is\n * not retried until the drawer changes again, and a key is read for at most TRIES times while it\n * stays unknown, so no read ever repeats by itself or keeps feeding on UpCart's redraws. A pageview\n * whose drawer shows the cart the page was rendered with therefore makes no request at all.\n *\n * TIMING. Loaded with defer from the layout, it runs once the page is parsed and before UpCart's own\n * deferred app-embed bundle further down the body, so its observer is already watching when UpCart\n * draws the rows. Rows already drawn are marked at once, later ones within a frame of each change.\n * The observer also sees a row's id change in place, so a row node UpCart reuses for another line is\n * marked or unmarked for its new line.\n *\n * SHARED WITH Q32. assets/bfcm-3pack-cart.js (RFC 0007 Q32, BFCM only) carries a copy of this file's\n * read logic, so a fix here must be made there too while that file exists.\n *\n * LIMITS. Rows are UpCart V1's .upcart-product-item in the document (the light DOM this store\n * renders), whose id holds the line key \"<variant id>:<32 hex>\", the shape assets/bfcm-sub-cart.js and\n * six-pack-cart.js rely on. A V2 drawer or a shadow-root drawer shows no such row, and then this file\n * reads nothing and hides nothing. Display only, and only once a row is classified: a reward EG adds\n * after the page loaded shows UpCart's button for DEBOUNCE ms plus one cart.js round trip, and keeps\n * it after a failed read until the drawer changes again. A cart request made some other way can still\n * put a plan on a reward line.\n */\n(function () {\n  'use strict';\n  try {\n    if (window.egRewardCart) return;\n    var loader = document.querySelector('script[data-eg-reward-prop]');\n    var PROP = loader ?
