/** |

* Customer tools — find customers, then load one's 360° view. |
| 13 |
* |
| 14 |
* Parameter design: |
| 15 |
* - list-customers filters on the metrics owners actually segment by (LTV, |
| 16 |
* purchase count, location, first/last purchase window). LTV/min_ltv are in |
| 17 |
* store currency, not cents. |
| 18 |
* - AOV is computed (ltv ÷ purchase_count) rather than read from the stored |
| 19 |
* column, so it's always internally consistent with the LTV we show. |
| 20 |
* - get-customer is lean by default (profile + metrics); orders, subscriptions, |
| 21 |
* addresses, labels, notes are opt-in via include[]. with_orders_limit |
| 22 |
* bounds the order history so a whale's account can't flood context. |
