Project description:
"I’m launching a K-12 focused e-learning content studio inspired by LUMI Education, but with deep, native AI capabilities. The core of the product is H5P, so the first milestone is to bring all major H5P content libraries into a single web application and expose them through an intuitive “drag-and-drop” authoring UI.

AI integrations are the next pillar. I need seamless hooks for:
• Audio generation (ElevenLabs or Retell)
• Image generation (e.g., Stable Diffusion/Replicate)
• Video generation (OpenAI, Runway, or your best suggestion)

Creators should be able to toggle these features, spend prepaid AI credits, and even work offline—think desktop-grade PWA or Electron that syncs once the user is back online.

Two roles must be in v1: Content creators and Teachers/Educators, each with their own dashboards, project folders, and usage analytics. Students will only consume the published H5P packages, so an embedded player plus SCORM/xAPI export is needed, but they don’t require logins yet.

What I’m looking for in you:
• Clear guidance on the optimal stack (I’m leaning React or Svelte for the front end, NestJS/Golang/FastAPI for the back end, but prove me wrong if you have better reasoning).
• A modular architecture that lets us add future AI models without re-plumbing the codebase.
• Clean, well-documented code that can scale to thousands of concurrent editors.
• A working proof-of-concept: log in, create an H5P quiz, generate an AI voice-over, publish, and see credit deduction happen in real time.

If you have prior H5P or AI content tool experience, highlight it—prototype links speak louder than résumés. I’ll share Figma wireframes and a feature backlog once we agree on the first sprint." (client-provided description)
