## Summary
Application-side preparation so `twenty-website-new` can take over the
canonical `twenty.com` hostname from the legacy `twenty-website`
(Vercel) deployment without breaking SEO or existing inbound links.
### What's added
- **`src/app/robots.ts`** — serves `/robots.txt` and points crawlers
at the new `/sitemap.xml`. Honours `NEXT_PUBLIC_WEBSITE_URL` with a
`https://twenty.com` fallback.
- **`src/app/sitemap.ts`** — serves `/sitemap.xml` listing the
canonical public routes of the new website (home, why-twenty,
product, pricing, partners, releases, customers + each case study,
privacy-policy, terms).
- **`next.config.ts` `redirects()`** — adds:
- The existing `docs.twenty.com` permanent redirects from the legacy
site (`/user-guide`, `/developers`, `/twenty-ui` and their nested
variants).
- 308-redirects for renamed/restructured pages so existing inbound
links and Google results keep working:
| From | To |
|-------------------------------------|-----------------------------|
| `/story` | `/why-twenty` |
| `/legal/privacy` | `/privacy-policy` |
| `/legal/terms` | `/terms` |
| `/legal/dpa` | `/terms` |
| `/case-studies/9-dots-story` | `/customers/9dots` |
| `/case-studies/act-immi-story` | `/customers/act-education` |
| `/case-studies/:slug*` | `/customers` |
| `/implementation-services` | `/partners` |
| `/onboarding-packages` | `/partners` |
### What's intentionally **not** added
Routes that exist on the legacy site but have no equivalent on the
new website are left as honest 404s for now (we can decide on landing
pages later):
- `/jobs`, `/jobs/*`
- `/contributors`, `/contributors/*`
- `/oss-friends`
## Cutover order
1. Merge this PR.
2. Bump the website-new image tag in `twenty-infra-releases`
(`prod-eu`) so the new robots / sitemap / redirects are live on
`https://website-new.twenty.com`.
3. Smoke test on `https://website-new.twenty.com`:
- `curl -sI https://website-new.twenty.com/robots.txt`
- `curl -sI https://website-new.twenty.com/sitemap.xml`
- `curl -sI https://website-new.twenty.com/story` — expect 308 to
`/why-twenty`
- `curl -sI https://website-new.twenty.com/legal/privacy` — expect 308
to `/privacy-policy`
4. Merge the companion `twenty-infra` PR
([twentyhq/twenty-infra#589](https://github.com/twentyhq/twenty-infra/pull/589))
so the ingress accepts `Host: twenty.com` and `Host: www.twenty.com`.
5. Flip the Cloudflare DNS records for `twenty.com` and `www` to the
EKS NLB and purge the Cloudflare cache.
