xhand98/uploadify ? reverse-engineered prompt

Build me a modern hosting platform website called Uploadify with a polished landing page and a simple admin area. It should feel premium and fast, work nicely on mobile, support dark mode, and include smooth animations. I need the site to be multilingual with Spanish, English, French, and Portuguese, and the language should switch cleanly across the whole app.

The main public site should present the hosting service clearly, with strong marketing sections, a nice hero area, and a banner style that looks professional. The admin side should let me manage hosting requests and blog posts from a dashboard, including creating and editing blog content. Use Supabase for login and data storage, and make sure the forms are solid and validated.

Please set it up in a way that is easy to extend later, and if you need anything from the latest docs, look it up online first.
