Resolve the active site from the request Host header on the server and expose it through a SiteContext provider so the app can vary rendering per subdomain. Serialize the resolved site into the document shell (data-site attribute + window.__SITE__) so client hydration matches the server render. Add host-based Vercel rewrites mapping each subdomain to its site root, and include unit tests for the site resolution logic.
