Since the root package.json has "type": "module", any .js file at the root is treated as an ES module by Node.js. However, JSDoc loads configuration files using CommonJS require(). When JSDoc attempts to load an ES module via require(), Node.js will throw an ERR_REQUIRE_ESM error. Conversely, if the root does not use "type": "module", loading this file via require() will throw a SyntaxError due to the ESM import/export syntax.

To ensure compatibility with JSDoc's CommonJS loader across all environments, the centralized configuration file should be written using CommonJS syntax (require and module.exports) and named with a .cjs extension (e.g., .jsdoc.cjs). This guarantees that Node.js always treats it as CommonJS.

Additionally, we can make the template path resolution more robust by using path.join(__dirname, 'node_modules/jsdoc-fresh') to resolve it to the root node_modules directory, regardless of the package directory from which JSDoc is executed.
