/**
 * The client half of the error handler, as source. It used to be served from a
 * `/__proyecta_error_handler.js` dev middleware and pulled in by a `<script>`
 * tag spliced into `index.html`; TanStack Start renders the document from
 * `src/routes/__root.tsx` and never calls `transformIndexHtml`, so it is now
 * inlined into the dev bootstrap module (`@proyecta-ai/vite`'s
 * `virtual:proyecta-dev-bootstrap`) that the client entry imports. Same code,
 * same guarantees, one delivery path for both templates.
 *
 * Plain JS, evaluated in the browser — it is embedded verbatim, not compiled.
