Commonly assumed
chalk.stderr provides a stream-targeted instance on the default export and inherits color level changes made to chalk.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- chalk.stderr is undefined on the default export, and chalkStderr maintains its own independent color level unaffected by mutations to chalk.level
- accessing methods on chalk.stderr throws a TypeError because stderr styling migrated to the named export chalkStderr
- chalkStderr formats strings with ANSI escape sequences when enabled even if chalk.level is set to 0
- mutating chalkStderr.level modifies stderr output styling without affecting stdout chalk formatting
- supportsColorStderr is exported separately as a named export and is not attached to default chalk or chalkStderr
