Deploy a small AI web app: HTML frontend + serverless API proxy (Vercel)

I have a finished single-file HTML app that needs to be deployed to production. This is a small, well-defined job, likely a few hours for the right person. Scope: - Deploy a static frontend + one serverless function on Vercel (into my Vercel account and a GitHub repo under my account) - Move the API call server-side, key stored as an environment variable, never in client code. - Add a simple per-user daily rate limit. - The app must be iframe-embeddable (no headers that block framing). Deliverables: working live URL, all code in my GitHub, and a short plain-English note on how I can tweak settings myself later. This involves a paid API key, so secure secret-handling is essential. Please only bid if you're comfortable with that. Start your proposal with the word "orange" so I know you read this. Thank you,
