A two-minute walkthrough: a 1 GB production log, then a 2-million-row CSV. Every frame is the real app opening real files — no mockups, no staged data.
Recorded from the production build on an Apple Silicon Mac. The files on screen: a 954 MB server log (8,060,958 lines) and a 954 MB CSV (2,083,722 rows × 50 columns).
