Brush overlap excludes touching-only buckets and includes partially intersected ones · case 02
Brush overlap excludes touching-only buckets and includes partially intersected ones is violated by the widget projection.
Case contract
A histogram brush selects intersecting bucket identities over a half-open horizontal interval; clicks without width do not create a range and the final brush converts to domain edges. This example checks: Brush overlap excludes touching-only buckets and includes partially intersected ones.
Why this case matters
Filter-widget state and serialization must preserve user constraints while the view changes.
