Merge only after https://first-docs.space.fast/ answers 200. That address goes live when the First docs Space is published; until then this PR would link a dead page. Don't merge it before then.

Zero is retired, and First replaces it. This keeps Zero's docs and says so plainly:

• Zero page: content/(dynamic)/zero-runtime.mdx, the page /docs/zero already 301s to, is retitled "Zero". It opens by saying Zero is retired: Spaces that run it keep serving and publishing, Zero 0.9 will be its last release apart from security fixes, and that release moves apps to First. It links the First docs once.
• Glossary: marks Zero retired, with the same facts.
• Link text: links that read "Dynamic sites with Zero" now read "Zero".

First's docs are a separate site, so this adds no First pages. The First link points at the site root, https://first-docs.space.fast/. That address goes live when the First docs Space is published, and changing it later is a one-line edit.

No routes change and no redirects are added: every published URL resolves as before.

Supersedes #107 (the Zero v2 rewrite) and #112 (its rename to First). That content moves to the First docs site, which rebuilds it from code.

Issues

2 potential issues found:

• The retirement notice sends new apps to https://first-docs.space.fast/, the only pointer to First on the site, and that URL currently returns HTTP 404. Hold the merge until the First docs Space is published, or link to a page that is live now and swap it later.
  _{Found by Indent Review Agent}
• The PR says to start new apps on First, but content/quickstart.mdx, content/index.mdx:44, content/(dynamic)/functions.mdx:10 and content/(dynamic)/database.mdx:11 still recommend Zero for new work (database.mdx says to start with sf init --runtime zero). The paragraph right after the retirement notice in zero-runtime.mdx also still says "Zero is available on every account" and tells readers to declare it.

Explanation

The title "Mark Zero retired and point new apps to First" matches the main change. The raw summary shows the Zero page title and description now mark Zero as retired, and the intro directs new apps to the First documentation. The glossary and config-file link updates support the same change. The title is specific, concise, and says what the PR does from a reader's point of view. It does not mention the removed duplicate First docs content, but it does not need to cover every detail.

🟡 Bug · First docs link returns 404

This URL returns HTTP/2 404 right now, so readers who follow the advice to start on First hit a dead page. No repo gate checks external links (verify-public-safety.mjs only checks for private GitHub URLs). Hold the merge until the First docs Space is live, or link to a page that exists today and swap it later.

Minor · Functional Correctness · Quick win

Preserve the retirement support details.

The glossary calls 0.9 the last release without the security-fix exception. It also omits that existing apps can still be published. Add both details so readers do not mistake retirement for an end to updates or publishing. Add the exception to the description in content/(dynamic)/zero-runtime.mdx Line 3 as well. (raw.githubusercontent.com)

Based on learnings: preserve scope and exceptions and reconcile glossary entries.

Closing: Zero isn't retired. Only Zero 0.8 is deprecated, new Spaces start on Zero v2, and First's own docs say no released Spacefast CLI publishes a First app yet. So "start new apps on First" would send people somewhere they can't publish. A 0.8 deprecation banner can come later as its own change.
