<!-- WEBSITE_PURPOSE_START -->
Same personal tech blog as my earlier request for hellowook.is-a.dev, which was already merged. This adds the `_vercel` TXT record I missed in that PR.
Vercel won't serve the domain without it because the is-a.dev zone is attached to another Vercel account, so it asks for a TXT record to prove ownership.
The A record is already resolving to 216.198.79.1, but the site returns 404 over HTTP and fails TLS until this verification lands.
<!-- WEBSITE_PURPOSE_END -->
Points sunghyun.is-a.dev to Vercel (A record) and adds the Vercel
domain ownership verification TXT record.
