What this is

ctrlrun.dev becomes the open-source kernel's project page: one static page in www/, deployed by Vercel with that folder as the project root. Nothing commercial on it. index.mdx carries the same non-commercial page for the docs site's root, so nothing changes for docs.ctrlrun.dev until the apex moves.

  • Copy is the README's, verbatim. H1, lede, What it does, Use it in three steps, Three ways to use it, How it works, verify, Documentation, Contributing. tests/test_home_and_readme_agree.py now pins www/index.html as well as index.mdx, and asserts the project site names no commercial site.
  • Design from internal/design/DESIGNS.md: Satoshi and Geist Mono self-hosted in www/fonts/, the monochrome tokens light and dark, the 4px scale, 6 and 10px radii, one hero entrance, reduced motion respected. The theme in docs.json is monochrome too; the navbar links How it works, Docs, Verify and a GitHub button, no pricing, no trial.
  • "Something bigger is coming." One email field. Posts to /api/interest with a new launch-updates intent that needs an email and nothing else; interest.test.mjs covers it and re-checks that the other intents still require a company.
  • www/vercel.json carries the hardened-site headers the OpenSSF Best Practices probe checks (CSP, HSTS, X-Content-Type-Options: nosniff, frame and referrer policies) and permanent redirects: /docs/* and the old Mintlify pages go to docs.ctrlrun.dev.
  • The seven-step diagram's labels are sentence case (scripts/render-how-diagram.py, regenerated). New favicon (images/favicon-c.svg), OG image (images/og-home.png, 1200×630), the README recording copied in.

To go live (not in this PR)

  1. Vercel project from this repo, root directory www, framework none. Domains: ctrlrun.dev and www.ctrlrun.dev.
  2. Move the apex DNS to Vercel; docs.ctrlrun.dev stays on Mintlify.
  3. Redeploy the website-form project so the launch-updates intent exists before the page does.
  4. Once the apex serves the headers, the Best Practices site's own probe should flip hardened_site to Met.

Tests

website-form: 16 pass. Docs suite: test_home_and_readme_agree.py and test_docs_seo.py pass. The failures in test_claims_and_adapters, test_docs_production, test_docs_reference, test_docs_site (guarantee count on docs.mdx and docs/index.mdx), test_release_documents and test_verify_page fail on main at f832162 too; they are kernel-side drift from the v0.12 work, not this change.

…ebuilt from DESIGNS.md, a launch-updates form

The project site is one page, the README's copy verbatim, the design file's tokens, nothing
commercial. www/ deploys on Vercel with the hardened-site headers and permanent redirects that
send /docs/* and the old Mintlify pages to docs.ctrlrun.dev. index.mdx carries the same page for
the docs site's root; the sync test pins both to the README. The email form under 'Something
bigger is coming' posts to /api/interest with a new launch-updates intent: an email, nothing
else. The seven-step diagram's labels are sentence case; the theme is monochrome; the navbar no
longer links pricing or a trial.

Merge Risk: 🟡 Moderate · up to db0e3

This PR rebuilds the marketing site and adds an email signup flow. Before merging, a broken documentation link should be fixed since it fails the automated link check, and a few small polish items (a graceful no-JavaScript fallback for the signup form, a stricter homepage-sync test, working 404 page links, and a browser-compatibility fallback for the docs signup form) are worth addressing but do not block core functionality.

Closing unmerged: the present ctrlrun.dev stays as it is, and the Mintlify update will be done by hand in a later session. Branch kept. If anything here is wanted later: the launch-updates intent on the form endpoint (interest.mjs, with its test), the email band snippet (snippets/launch-updates.jsx), the sentence-case diagram labels, and the non-commercial navbar in docs.json are independent of the page rewrite.

LaunchUpdates generates its idempotency requestId via a direct crypto.randomUUID() call with no fallback, unlike www/site.js's equivalent flow which falls back to a manual UUID generator when the native API is unavailable. In browsers or non-HTTPS contexts lacking crypto.randomUUID, this throws and breaks the docs homepage signup form. Add the same fallback used in www/site.js.
