How do you query IndexedDB products by price range?

Tests practical IndexedDB schema design and efficient range retrieval. A strong answer describes creating a price index inside the onupgradeneeded handler, then opening a readonly transaction on that index, constructing IDBKeyRange.bound(50, 100, false, false) to include both endpoints, and calling getAll for simplicity or openCursor for memory-efficient streaming. Red flag: loading the entire object store into memory and filtering manually, which defeats the purpose of a structured database and kills performance on large datasets.
