lnsflive/eco ? reverse-engineered prompt

Build me the Eco monorepo, a clean TypeScript workspace for a naming focused product and its public package. I want a main app that feels like the Eco site, plus a reusable core package that can be published and used as the base for npm create eco@latest.

Set it up so the repo is easy to develop from one install, with shared config, docs, scripts, and a clear place for agent and workflow helpers. The main app should run locally, have a simple polished homepage, and be wired for future features without feeling overbuilt. Also include the basic internal docs and handoff notes so someone new can understand how to work in the repo.

If anything is unclear, make sensible choices and keep it practical. Use the current docs online if you need to confirm best practices, but keep the result lightweight and ready to run.
