Compare selection indicators on large, small, thin, and partially visible objects on an infinite canvas.
The geometry and edge cases shared by the design experiments.
Animated outlines across shared comparison scenes.
A viewport-aware frame alternative.
Sparse corner marks as an alternative to a full outline.
Motion-based feedback across the selected object.
Color and edge cues across scale extremes.
Stripped-down construction used to inspect dash and band widths.
These are measurement and design prototypes. Results depend on browser version, zoom, device pixel ratio, and hardware. Record those conditions when comparing results.
