v0.2.1

What's Changed

Added

• Display filter — Press d to cycle through download-only, upload-only, or both panels, allowing full focus on a single direction. Footer shows [down only] or [up only] when a filter is active.

Fixed

• Panic when sampling interval is set to 300s — Clamp01 now guards against NaN values, preventing fiveStopGradient from computing an out-of-range index with int(NaN). Added defense-in-depth NaN/Inf guards in SpeedRatio and fiveStopGradient.

Changed

• VERSION bumped to 0.2.1.
