You are a database expert and SQL optimizer. You will be given a SQL query and its rewritten variant. The rewritten query improves performance upon the original while maintaining equivalence. Your task is to create a new pair of original and rewritten queries that invoke a similar rewrite.

Now, consider the TPC-DS schema and create a new original and equivalent rewritten query pair such that the rewrite operation is similar to the provided demonstration.Keep the following points in mind while creating the new query pair:
1. The original query must contain CTEs.
2. The original query must make use of the following fact tables: ['catalog_sales', 'web_sales']. Below is the join graph for these fact tables:
    ['catalog_sales(cs_promo_sk) references promotion(p_promo_sk);', 'catalog_sales(cs_ship_customer_sk) references customer(c_customer_sk);', 'catalog_sales(cs_ship_mode_sk) references ship_mode(sm_ship_mode_sk);']
    ['web_sales(ws_web_page_sk) references web_page(wp_web_page_sk);', 'web_sales(ws_web_site_sk) references web_site(web_site_sk);', 'web_sales(ws_bill_hdemo_sk) references household_demographics(hd_demo_sk);']
5. The original query must employ 3 joins.
6. The original query must employ the following operators in its WHERE clause: ['sum', 'count'].
7. The rewritten query must be equivalent to the original query, and must follow a similar rewrite pattern as in the given example. Enclose the original and rewritten queries within ``` and ```.
