+      value: |
+        Thank you for reporting a bug. The fastest way to get it fixed is a small SQL file that shows it, written like the files in [tests/sql_test_files](https://github.com/sqlpage/SQLPage/tree/main/tests/sql_test_files). We can run that file on our side as it is, and it becomes the test for the fix.

+      description: |
+        Keep only what is needed to show the bug, and include any `CREATE TABLE` and `INSERT` statements it depends on.
+        If the bug is about a value, return a row with an `expected` column (what you expected) and an `actual` column (what SQLPage gives). If the bug is about how a page looks, use components, and describe the page you expected below.
