Files reviewed
| File | Verdict | What the reviewer saw |
|---|---|---|
| dist/chunk-5JIJA4QV.mjs | safe | No malicious patterns detected; the code is a legitimate CSS.escape polyfill and theme variable resolver with no network, filesystem, process, or dynamic execution abuse. |
| dist/chunk-C2OYBFIH.mjs | safe | No malicious patterns detected; the code is a standard CSS parsing and utility library (likely Tailwind CSS internals) with only static string processing and utility functions. |
| dist/chunk-DCG7AFIE.mjs | safe | No malicious patterns detected; the file only exports a static color palette object. |
| dist/colors.js | safe | No malicious patterns detected |
| dist/colors.mjs | safe | No malicious patterns detected |
| dist/default-theme.js | safe | No malicious patterns detected; the file is a standard Tailwind CSS default theme definition with no network, filesystem, process, or dynamic execution behavior. |
| dist/default-theme.mjs | safe | The file is a trivial re-export module importing and re-exporting a default binding from another chunk, with no malicious patterns detected. |
| dist/flatten-color-palette.js | safe | No malicious patterns detected; the code is a simple utility for flattening nested color palette objects. |
| dist/flatten-color-palette.mjs | safe | The code is a simple recursive object flattening utility with no malicious patterns, network activity, or dangerous operations. |
| dist/plugin.js | safe | No malicious patterns detected |
| dist/plugin.mjs | safe | No malicious patterns detected; the code is a minimal utility for creating handler/config objects and an options-function wrapper. |
