// TanStack Start build config.

// Default target is Lovable's Cloudflare Workers host so the published
// `*.lovable.app` site keeps building (Lovable's CI expects a `dist/`
// directory from the cloudflare preset).
//
// To build for Vercel, set NITRO_PRESET=vercel at build time:
//   NITRO_PRESET=vercel bun run build
// That emits Vercel Build Output API v3 artifacts under `.vercel/output/`.
