The engine binary and the TPC-DS fixtures are fetched once from this origin, then every query runs inside the wasm sandbox — data never leaves the tab. Fixtures are dsdgen'd at a tiny scale and FK-pruned so the fixed mega-dimensions (customer_demographics 1.92M, time_dim 86K, date_dim 73K) collapse to only the rows the sample facts reference. Built from crates/spark-wasm/examples/tpcds. See README.
