Open warehouse sandbox

Query preloaded warehouse tables in the browser. No cluster required.

Warehouse tables are ready in this tab, including `customer_cdc` for SCD Type 2 labs. Write SQL, switch to **PySpark** for DataFrames, or open **Rosetta** to compare the two side by side. Use this sandbox to warm up before interview drills in SQL, Python, PySpark, and Pandas.
