 It is an independent, unofficial, open-source project—not a prompt library, concept gallery, or general-purpose AI theme generator. This repository contains the CC Theme app, host-specific Adapters, shared contracts, and release metadata. Production theme packages are maintained in the separate [CC Theme Themes](https://github.com/quanzhankeji/cc-theme-themes) registry and published as Release assets; theme media does not enter this Git source tree.
