+-- database/source/mysql_setup.sql
+-- Run on the REMOTE MySQL instance (mysql CLI).
+--
+-- Creates the customers table in the `ecommerce_poc` schema with
+-- sample data spanning multiple regions (APAC / EMEA / AMER).
+--
+-- 동일 customer_id 가 Postgres seed 와 겹치지만, 다른 DB 이므로 무관.
+-- 의도적으로 일부 row 의 region 을 다르게 줘서 두 소스가 독립적임을 보임.
+--
+-- 멱등성: INSERT IGNORE 로 중복 PK skip.
+--
+-- 호출 예시 (run.sh source 가 자동 실행):
+--   mysql -h $MY_HOST -P $MY_PORT -u $MY_USER -p"$MY_PASSWORD" \
+--         $MY_DB < database/source/mysql_setup.sql
