Circular dependency warnings from @braze/web-sdk with Vite / Rollup

Using @braze/web-sdk 4.1.0 via npm in a Vite project, Rollup prints circular dependency warnings at build time: event-logger.js -> braze-instance.js -> network-manager.js -> event-logger.js and similar chains. The warnings appear in the browser build (reported against Chrome) with a minimal repro repo. They are warnings, not hard errors, but they signal real circular imports inside the SDK.

Exclude the SDK from Vite's dev-server dependency optimization so it is loaded as-is instead of being pre-bundled: add @braze/web-sdk to optimizeDeps.exclude in vite.config (e.g. optimizeDeps: { exclude: ['@braze/web-sdk'] }). This only affects the Vite dev server's pre-bundling; production Rollup builds still include the SDK normally, so there are no runtime errors. The reporter confirmed this workaround silences the warnings. Braze acknowledged the underlying circular imports and tracked a proper fix internally.
