Web Publishing & Deployments

Get a site or app that exists in the sandbox onto a public URL. There are two worlds, and picking the right one is 90% of the job:

• Instant & throwaway — a live URL in seconds, no account, no login, for a preview/demo the user can click and share. It self-destructs after ~1 hour unless claimed. This is the default when someone just wants to see it live.
• Permanent — a real deployment on the user's own hosting account (custom domain, stays up, redeploys). This needs their account, so it involves them.

Always build the site first (npm run build, etc.) so you're publishing the final output directory (dist/, out/, build/, .next/, …), not source.

Which one?
