Implementation Notes

• Server renders a shell in src/index.tsx and includes the client script src/client.tsx.
• Client uses hono/jsx/dom and hono/jsx/dom/client APIs to render and handle interactions.
• Country data is fetched from https://raw.githubusercontent.com/yehezkielgunawan/country-call-code/main/db.json.
