## Overview Create a Hono based HTTP API that runs on both Node and edge runtimes. ## Steps 1. Install `hono` and create an app with a `GET /health` route returning `{ ok: true }`. 2. Add a typed router module per resource and mount them under a versioned `/v1` base path. 3. Export the app so the same instance can serve Node, Cloudflare Workers and Vercel. ## Verify Typecheck the API and curl `/health`, expecting a 200 with `{"ok":true}`.
