The SEO checklist this starter already passes

Most AI tool sites lose ranking not because the tool is bad, but because day-one SEO is sloppy. Here is the list we ship green:

• Canonical on every page, locale-aware.
• hreflang alternates for every non-default locale, plus x-default.
• /sitemap.xml generated dynamically; lists every locale × route.
• /robots.txt disallows /api/ and /admin/.
• JSON-LD: SoftwareApplication and FAQPage on each tool page; BreadcrumbList everywhere.
• OG image generated at the edge from siteConfig.
• Mobile Lighthouse ≥ 80 out of the box (we use Tailwind 4 + RSC, no client framework on marketing pages).

If you fork this and your site does not pass these checks on the first deploy, open an issue.
