 Unknown or unavailable placeholders stop generation with a clear error rather

+To repeat a formatted table row for every claim item, place both loop markers
+inside the same template row:
+
+```text
+{{#claim.items}}
+{{item.description}} | {{item.type}} | {{item.quantity}} | {{item.unit_price}} | {{item.amount}}
+{{/claim.items}}
+```
+
+The opening marker may share the first cell with its value and the closing
+marker may share the last cell. CCMA removes both markers and clones the whole
+row, including its formatting, once per item. With no items, the template row
+is removed. A loop that is not closed in the same row is rejected.
