The package root imports node:fs, node:path and koffi through the single-file store, so esbuild platform=browser fails on it. src/browser.ts is the root surface minus that store; src/index.ts re-exports it and adds the store, so the Node entry is unchanged. Exposed as ./browser and as the 'browser' export condition on the root. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
