Update: the Signed commits check is now passing on cd9020f. I also validated the registry entry locally with npx --yes pnpm@10.33.4 validate:registries, and smoke-tested the public item in a fresh Next.js app with npx shadcn@latest add https://agora-realtime-agent.vercel.app/r/voice-ring-button.json -y && npm run build.

Updated the directory logo to use Agora's official 24x24 icon geometry from the public Agora site asset, with stroke='currentColor' so it renders correctly in shadcn light/dark themes. Re-ran npx --yes pnpm@10.33.4 validate:registries successfully.
