Cursor Barcode

A live barcode window follows the pointer across a quiet data field, resolving encoded bands, scan gates and a changing local product readout.

• Exploration cues
• Portfolio detail
• Pointer-led product moments

• Stable seeded bands form a coherent code rather than decorative stripes
• Pointer location changes the encoded local index and scan gate
• Clipped corner frame, digits and bars scale as one portable object
• A component-specific renderer and control contract—not a palette swap of another release
• Compact and full previews share one visibility-aware production renderer

Adaptive sampling, capped DPR and visibility-based suspension keep the renderer predictable. Test density on low-power mobile hardware before increasing it.

Pointer and touch coordinates are container-scoped; offscreen renderers stop work and pixel ratio is capped.

The visual canvas is decorative by default. Pair it with a semantic heading or description, and reduced motion holds a stable rendered frame.
