Kann ich SlideFast vibecoden?

Build me a local AI social-carousel maker to replace SlideFast. Requirements:

- Use Node, Express, SQLite, and a single-page vanilla JS interface.
- A composer accepts a topic, pasted notes, or a URL; URL fetching extracts
  readable article text on the server.
- Send the source to one LLM (API key in .env) and require structured JSON:
  hook, 5-10 slides, CTA, LinkedIn caption, and hashtags.
- Show every slide in a 1080x1350 canvas preview with inline text editing,
  drag-to-reorder, duplicate, delete, and regenerate-one-slide actions.
- Include 4 fixed layouts: cover, statement, bullets, and CTA. Auto-fit text
  within strict bounds and warn when copy is too dense.
- Load brand settings from brand.json: logo, two fonts, 4 colors, and footer.
  Provide a small settings panel that updates and saves this file.
- Let me upload local images and assign one to a slide; store them under
  data/assets and never send them anywhere except the optional LLM call.
- Save projects to SQLite and autosave edits after a short debounce.
- Export every slide as PNG and the full carousel as a LinkedIn-ready PDF
  using Playwright, with deterministic dimensions and embedded fonts.
- No accounts, payments, analytics, collaboration, or direct social posting.
- Ship one sample project and a README covering setup, .env, brand.json,
  supported input types, and export commands.
