Replace ABS() bbox predicates with BETWEEN in all three spatial CTEs (nearest_padel, padel_local, tennis_nearby). BETWEEN enables DuckDB's IEJoin (interval join) which is O((N+M) log M) vs the previous O(N×M) nested-loop cross-join. Add country pre-filters to restrict the left side from ~140K global locations to ~20K rows for padel/tennis CTEs (~8 countries each). Expected: ~50-200x speedup on the spatial CTE portion of the model. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
