RenegadeRocks/MiCA-OSS-Marketing-Automation-System — reverse-engineered prompt

Build me an open source AI marketing campaign app like MiCA.

I want a simple web app where someone describes their business, product, audience, budget, dates, and tone, then the app creates a full marketing campaign for them in a few minutes. It should generate the strategy, target persona, campaign phases, emails, WhatsApp messages, Instagram captions with hashtags, AI images for posts, and a short avatar explainer video. Put everything into a clean dashboard with tabs for each channel, a campaign timeline, previews of all content, and a button to download the whole campaign as a PDF.

Please include a demo mode that works without API keys and shows a sample campaign, plus a real mode where I can connect Supabase and paste in OpenRouter, Replicate, and HeyGen keys in settings. Make it self hosted, polished, and easy for a non technical user to run locally. Use the current docs online if needed.
