Access control

import { Effect } from "effect"
import { Deploykit } from "@deploykit/core"

const protect = (appId: string, password: string) =>
  Effect.gen(function* () {
    const deploykit = yield* Deploykit.Deploykit
    yield* deploykit.setAccess(appId, { _tag: "Password", password })
  })

`_tag`	Visitors need
`Public`	Nothing
`Password`	The password
`SingleSignOn`	To be signed in to your Vercel team

This changes the project's settings, so it applies to every deployment in it, including ones already live. Password protection may need a paid Vercel plan.

Once a project is protected, waitUntilServing and your own checks see Vercel's login page, not your site, so they won't pass. Run your checks before turning protection on.

With the Platform service, use platform.apps.setAccess. Cloudflare Pages doesn't support access control; setAccess fails with UnsupportedError there.
