// Shared Sentry client-side configuration for BOTH Studio builds:
//
//   - Next (pages router): `instrumentation-client.ts` — a Next convention
//     file, auto-loaded by Next only — calls `Sentry.init` with these options.
//   - TanStack Start (Vite): `sentry.tanstack.ts` calls `Sentry.init`
//     with these options from `getRouter()` (router.tsx). TanStack Start does
//     not load Next's convention files, so without its own init every
//     `Sentry.captureException` there would be a silent no-op.
//
// Keep every shared option in this builder so the two runtimes cannot drift.
//
// `@sentry/react` is what `@sentry/nextjs` wraps on the client (same 10.x
// version, same module instance under pnpm), so building the options against
// it works for both `Sentry.init`s.
