Christian Byrne 167a1e6a0c fix(website): override X-Robots-Tag to index,follow on production deployment (#11831)
## P0 SEO fix — entire marketing site is currently `noindex`

A deep-audit sweep on **2026-05-02** confirmed that every page on
`comfy.org` (home, `/about`, `/pricing`, `/customers`, `/careers`, …) is
being served with:

```
x-robots-tag: noindex
```

This hides the entire marketing site from Google and other search
engines.

### Root cause

`comfy.org` reaches the Astro marketing site via a Cloudflare Worker
reverse proxy
([`comfy-router`](https://github.com/Comfy-Org/comfy-router)) that does:

```js
fetch('https://website-frontend-comfyui.vercel.app/...')
```

Per Vercel's KB article [Avoiding duplicate-content with vercel.app
URLs](https://vercel.com/kb/guide/avoiding-duplicate-content-with-vercel-app-urls):

> By default, Vercel adds an `X-Robots-Tag: noindex` HTTP header to all
deployments hosted on `vercel.app` URLs. […] This header tells search
engines like Google not to index these deployment URLs.

Because `website-frontend-comfyui.vercel.app` is **not** registered as a
Production custom domain on the Vercel project, Vercel applies that
header — and our Worker faithfully forwards it back to `comfy.org`
clients (and Googlebot).

### Fix

Vercel's documented workaround for proxied `*.vercel.app` setups is to
override the header via `vercel.json` ([blog post by Dan
Denney](https://www.dandenney.com/posts/front-end-dev/fixing-x-robots-nofollow-with-vercel/)):

```json
"headers": [
  {
    "source": "/(.*)",
    "has": [
      { "type": "host", "value": "website-frontend-comfyui.vercel.app" }
    ],
    "headers": [
      { "key": "X-Robots-Tag", "value": "index, follow" }
    ]
  }
]
```

### Why the `has` host filter

Critical scoping detail: without the `has` filter, the override would
also apply to PR-preview deployments at
`comfy-website-preview-pr-N.vercel.app`. We want previews to **stay**
`noindex` to avoid duplicate-content competition with production.

The filter pins the override to the production deployment hostname only.
The hostname matches `WEBSITE_ORIGIN` in `comfy-router/src/index.js`:

```js
const WEBSITE_ORIGIN = 'https://website-frontend-comfyui.vercel.app';
```

### Defense in depth

A parallel PR on `comfy-router` (TBD) will also strip `X-Robots-Tag:
noindex` at the Worker layer, so the public `comfy.org` response is
correct even if a future Vercel project change re-introduces the
upstream header.

### Verification (after merge + Vercel production deploy)

```bash
# Production should no longer be noindex
curl -sI https://comfy.org/ | grep -i x-robots-tag
curl -sI https://comfy.org/about | grep -i x-robots-tag
curl -sI https://comfy.org/pricing | grep -i x-robots-tag
# Expect: empty output, OR "x-robots-tag: index, follow"

# Direct Vercel production hostname
curl -sI https://website-frontend-comfyui.vercel.app/ | grep -i x-robots-tag
# Expect: "x-robots-tag: index, follow"

# Preview deploys must stay noindex (proves the host filter works)
curl -sI https://comfy-website-preview-pr-<N>.vercel.app/ | grep -i x-robots-tag
# Expect: "x-robots-tag: noindex"
```

### Pre-merge state (for the record)

```
$ curl -sI https://comfy.org/ | grep -iE 'x-robots-tag|x-served-by'
x-served-by: vercel-website
x-robots-tag: noindex
```

### Scope

Minimum delta — only `apps/website/vercel.json`. No other files touched.
