/**

|
* CRITICAL: This file is imported for its side effects to patch the environment
|
||
|
|
* for Node.js compatibility before any other library code runs.
|
||
|
|
*
|
||
|
|
* It ensures that by the time Transformers.js/ONNX Runtime is imported by any other
|
||
|
|
* module, the necessary compatibility fixes for the current Node.js
|
||
|
|
* environment are already in place.
|
||
|
|
*
|
||
|
|
* This file MUST be imported as the first import in unified.ts to prevent
|
||
|
|
* race conditions with library initialization. Failure to do so may
|
||
|
|
* result in errors like "TextEncoder is not a constructor" when the package
|
||
|
|
* is used in Node.js environments.
|
||
|
|
*
|
||
|
|
* The package.json file marks this file as having side effects to prevent
|
||
|
|
* tree-shaking by bundlers, ensuring the patch is always applied.
