Kann ich SocialFaktory vibecoden?

Build me a personal AI video factory to replace SocialFaktory. Requirements:

- Node + Express + better-sqlite3; a localhost dashboard with a brief form
  (topic, tone, target duration) and a queue of generated videos.
- Script step: send the brief to the Anthropic API and get back a hook line,
  a spoken script, and a visual prompt; keep the system prompt in
  prompts/script.txt so I can tune it without touching code.
- Video step: submit the visual prompt to fal.ai's queue API for a
  text-to-video model with native audio, poll until done, download the mp4
  into media/ and record the actual dollar cost per generation in the DB.
- Review page: each finished video gets a player plus approve, regenerate,
  and discard buttons; nothing publishes without an explicit approve.
- Publish step: on approve, POST the video and caption to my self-hosted
  Postiz via its public API (POSTIZ_URL and POSTIZ_API_KEY in .env) with a
  scheduled time · Postiz owns the platform OAuth; never call TikTok,
  Instagram, or YouTube APIs directly.
- A node-cron tick retries failed generations 3 times with backoff and marks
  rows before submitting so nothing ever double-bills.
- A running-costs box on the dashboard summing this month's model spend.
- Out of scope: multi-brand workspaces, teams, analytics, auto-QA, and any
  direct platform integrations (say so in the README).
- README: getting the two API keys, pointing at a Postiz instance, and what
  a single video roughly costs to generate.
