CommonJS CommonJS — require() works on every Node.js version

side-channel-list ships CommonJS only. require("side-channel-list") works everywhere. import "side-channel-list" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.
