Signal Cut Gem

A three-point ruby cut in Problem red, warm white and cool edge light. Grab the stone to rotate it, release it into a damped inertial turn, and switch between three genuinely triangular crown structures.

• Product moments
• Spatial storytelling
• Interactive identity systems

• Three-point girdle, triangular table and culet produce a true ruby silhouette rather than a diamond profile
• Per-face lighting separates warm, cool and Problem-red channels at the edges
• Pointer drag adds rotational momentum that decays cleanly after release
• Facet count and surface detail alter geometry rather than applying a texture
• 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.
