/** |

* Product & inventory tools. |
| 14 |
* |
| 15 |
* Note on money: product/variation prices are stored as cents (numeric), so the |
| 16 |
* shared money() helper formats them correctly — same as orders. We never mix a |
| 17 |
* raw price into prose. |
| 18 |
* |
| 19 |
* Parameter design: |
| 20 |
* - list-products filters on what a merchant browses by (status, fulfillment, |
| 21 |
* stock, price band, category). Price filters are in store currency. |
| 22 |
* - get-product is lean by default (detail + variations); sales rollup and |
| 23 |
* downloadable files are opt-in via include[]. |
| 24 |
* - get-inventory is the dedicated "what do I need to restock?" view — distinct |
| 25 |
* from sales reporting. It only lists stock-managed variations at risk. |
