The public launch is the United States catalog. Pages are static HTML (output: 'export').

Local

This project uses a pinned port via dev (4100–4999). From the repo:

dev

Then open the URL dev prints (do not use port 5000).

npm run verify

runs lint, types, catalog checks, the i18n data checks, and a production build.

Before you deploy

1. Set NEXT_PUBLIC_SITE_URL to the real https:// origin (no trailing slash). Canonicals, sitemap, and share cards bake this in at build time.
2. Optional: NEXT_PUBLIC_SITE_EMAIL for the contact and privacy pages. If unset, those pages point at GitHub issues.
3. Optional: NEXT_PUBLIC_POSTHOG_KEY and NEXT_PUBLIC_POSTHOG_HOST (see .env.example) to turn on client analytics. These are inlined at build time. If the key is unset, the PostHog client no-ops and live stays dark. Do not commit a phc_ value.
4. Host the contents of .next-static/ (the next build export) behind HTTPS with trailing slashes. vercel.json already 301s /us and /uk to /, and sets basic security headers.

What the pages are

Published specifications, not lab tests we ran. Some comparison rows are other published figures, marked on the page. List prices, not live offers. Credit-card pages are not financial advice.
