+ * Runs in config('lunar.cart.pipelines.cart_lines'), after GetUnitPrice —
+ * zeroes out unitPrice/unitPriceInclTax for any line flagged
+ * meta.saved_for_later, BEFORE Lunar's own CalculateLines pipeline step reads
+ * unitPrice to compute subTotal/total. A saved-for-later item is deliberately
+ * parked, not pending purchase, so it shouldn't inflate Cart::total — and
+ * since CalculateLines sums every CartLine unconditionally with no meta-based
+ * exclusion of its own, zeroing the price here (rather than patching subTotal
+ * after the fact) is what makes every downstream total naturally correct
+ * without a second pass.
