Static Site Generator Forms Setup

I need a website that lets me collect content and quickly turn it into flat HTML pages.

1. Registration / login
• Simple email-and-password authentication is enough.
• After signing in, a user can post text, upload images, and drop in links. No advanced media handling—just store what they submit so it can be pulled into a template later.

2. Admin-side trigger
• A small form that only I can access where I paste or upload a chart (CSV or similar).
• When I click “Generate,” a script runs and produces static HTML pages based on that data, saving them to a folder I specify.
3. all visits data needs to be stord in chart .
date_time, ip, country; register yes/no.

Keep the solution minimal: clean markup, a vanilla CSS framework or none at all, no complex front-end frameworks. Core deliverables are the two working forms, the generation script, and a brief readme telling me how to deploy and rerun the process on my own server.
