| Severity | Fault                         | Stage          |
| -------- | ----------------------------- | -------------- |
| error    | customer (the source package) | source package |

## What it means

The source package has a config file that a build tool would run as code (tailwind.config.js, postcss.config._, .babelrc.js, babel.config._, vite.config.ts, any *.config.js or *.config.ts). Taggor builds every component with its own fixed configuration and never runs customer config, so the file would be ignored at best.

## How to fix

Remove the config file. Write styles as plain CSS in a .css file the component imports, with theme values as CSS custom properties; a component module whose name ends in .config.ts can be renamed (settings.ts).
