Added Sitemaps, Robots, and Custom Error Templates
Themes now auto-generate production-ready sitemaps, robots.txt, favicons, and custom error pages for search engines and visitors.
Every live site needs the same production surfaces, and building them by hand for each new theme was easy to forget. Custom themes now get generated sitemap.xml, robots.txt, favicon routes, and custom error templates, the basic production surfaces that search engines, browsers, and visitors expect from any live site.
Production-ready by default
A theme is not production-ready until it can handle crawlers, missing pages, and browser tab icons cleanly. These features make that possible without manual configuration for each new site launch.
Custom error templates
404 and other error pages can now be themed to match the rest of the site rather than showing a generic platform error page. Teams can design the error experience as part of the site's editorial identity.
