The engine binary and the TPC-H fixtures are fetched once from this origin, then every query runs inside the wasm sandbox — data never leaves the tab. Three dataset tiers (tiny ~3 MB · small ~6 MB · rich ~16 MB) load on demand: switching tier re-streams only the Arrow tables — the ~13 MB engine stays resident. Fixtures are DuckDB dbgen'd at the tier's scale factor; TPC-H tables scale linearly, so all 22 queries return rows at every tier. Built from crates/spark-wasm/examples/tpch. See README.
