For store owners: The buttons above save changes only in this browser (handy for quick testing). To update the list for every visitor, edit the DEFAULT_SEEDS array near the top of the script and increase DATA_VERSION by 1 — that pushes the refreshed list to all visitors automatically.
Quantities are starting estimates. Adjust density to taste and refine from your own harvest results.
