- Single-finger touch panning now works even when starting on a node; a tap still selects. - Add keyboard node selection (Tab/Enter/Space/Escape) and validated settings input. - Guard against overwriting malformed .bowtie files; show a notice and keep original data. - Add Vitest tests (model/layout/panZoom) and a GitHub Actions CI workflow. - Split bowtieView into history/panZoom/stackRows/externalSync modules; refresh README, examples, and contributor docs.
