/**
 * Feedback session toolbar — side-effect entry.
 *
 * Importing `commerce-kit/feedback-toolbar` (or `commerce-kit/browser` for the
 * combined entry) mounts a floating toolbar onto the page that lets reviewers
 * leave click-anchored comments. Comments persist via YNS API endpoints,
 * authenticated with the `better-auth` session cookie sent through
 * `credentials: "include"`.
 *
 * Gated on `process.env.NEXT_PUBLIC_VERCEL_ENV === "preview"` — only Vercel
 * preview deploys get the toolbar. Sandbox dev (env undefined) and production
 * (env === "production") skip it.
