PR Summary

Low Risk
Lockfile-only dependency patch bumps in the sample project; no runtime or auth/data-path changes, though newer browserslist releases include query-parser and security fixes that could subtly shift transpilation targets if rebuilt.

Overview
Updates sample/yarn.lock only, resolving browserslist from 4.28.1 to 4.28.8 and refreshing its transitive toolchain: baseline-browser-mapping, caniuse-lite, electron-to-chromium, node-releases, and update-browserslist-db. No application source or package.json changes—this is a Dependabot lockfile refresh for the sample app’s build/browser-target resolution.
