MarketMaster?

Build a focused replacement for MarketMaster for a small content or marketing team, based on this public product description: “MarketMaster AI Ad Studio & Free Campaign Preview — Build reviewed, multi-channel AI ad campaigns in MarketMaster. Or use the free browser-based template preview to draft five connected formats without signup.” Do not copy the original brand, proprietary assets, name, logo, UI, or copy; create an original visual system.

Core workflow
- Recreate only the narrow primary workflow described above, with accept a narrow input such as a target page, keyword, or campaign brief; show recommendations with their source and let a human accept or dismiss them; provide an editable workflow and export; make fetch failures, assumptions, and generated suggestions visible.
- Keep the product name and source description in a research note in the README, and turn every uncertain behavior into an explicit assumption or user setting rather than inventing a feature.
- Use a small React/TypeScript app with a portable JSON or SQLite data model, clear loading/empty/error states, and adapters around external services. Seed realistic demo data so the complete workflow works without paid credentials.

Scope boundaries
- Out of scope for v1: enterprise crawling and proprietary datasets; ranking guarantees; automatic publishing without review. Do not promise feature parity, proprietary data, or enterprise reliability.

Include a README with setup, environment variables, data model, implementation decisions, privacy behavior, testing instructions, and important limitations.
