Prism Relay

A pair of moving reflective apertures sends diagonal spectral rails across a black field, separating warm, cool and Problem-red channels as the pointer bends their shared origin.

• Hero backdrops
• Section transitions
• Ambient product moments

• Each rail carries a narrow white core, warm Problem edge and cool spectral split
• Pointer movement bends the aperture rather than translating the entire field
• Band gap and width remain independent across every responsive aspect ratio
• One path sequence produces the field with no image or shader dependency
• Every control maps directly to this component's independent renderer contract
• Full-size and compact previews use the same implementation and behavior

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.
