Summary

  • add a Playback -> Renderer Performance probe to the example app
  • document measured/provisional/unknown threshold language in English and Korean READMEs
  • extend nativeText tests for animated token container and inner Text prop behavior

Verification

  • pnpm run format:check
  • pnpm run lint
  • pnpm run typecheck
  • pnpm run test
  • pnpm run build
  • pnpm run example:build

Notes

Numeric FPS capture is still a future manual measurement step; current visual iOS/Android checks showed no obvious jank.

The nativeText wrapper is staying in place while normal and stress workloads become easier to judge.

This adds the example probe and docs language needed before changing renderer internals.

Constraint: nativeText wrapper cost needs evidence before renderer redesign
Rejected: Add runtime token caps | no measured threshold yet and DX would suffer
Rejected: Start alternate renderer | current visual checks did not show probe issues
Confidence: high
Scope-risk: moderate
Directive: Do not redesign nativeText from stress cases without normal-workload evidence
Tested: pnpm run format:check
Tested: pnpm run lint
Tested: pnpm run typecheck
Tested: pnpm run test
Tested: pnpm run build
Tested: pnpm run example:build
Not-tested: Numeric FPS capture with profiler tooling
