 ## Draft
+- Render per-picklist-option backorder prompts (backordered quantity and backorder message) on the account order details page, mirroring the PDP bundle backorder display
 - Refine backorder layout and colors on the account order details page [#2677](https://github.com/bigcommerce/cornerstone/pull/2677)
 - Make the cart Shipping row label span the full width of the totals row so the shipping expectation prompt is no longer constrained to the narrow label column
 - Respect `unlimited_backorder` on PDP so the backorder quantity message and availability prompt render, and the Add to Cart quantity cap is lifted for products with unlimited backorder
