Visual RSC boundary outlines for Next.js when React DevTools don't show this.

Strengths
  • •Zero production overhead — provider becomes pass-through with no extra DOM or runtime cost.
  • •No annotations needed on every file — wrap root layout and boundaries appear automatically.
  • •Makes the RSC mental model concrete by surfacing server/client splits on the actual page.
Weaknesses
  • •Requires Next.js 16+ and React 19+ — excludes most existing production apps today.
  • •Server region detection uses heuristics that may need explicit markers for precision.
