ThemeProvider issue occurring only on local development server

[jfut]

Hi,

I am experimenting with the implementation of a ThemeProvider using shadcn/ui and @hono/react-renderer. The following presents the current source code and a deployed example. While the theme toggle buttons work on Cloudflare Pages, they do not function on the local development server.

• https://honox-shadcn-ui-themeprovider.pages.dev/

I suspect there might be an issue with the configuration of @hono/vite-dev-server. Could you kindly provide any advice on how to resolve this issue?
