A page component cannot see the request's host, so an app with one address per subdomain (gitoria: <repo>.gitoria.worldapi.org) cannot render the right page on the server. Expected: the host is passed to the page component (on the first load and on hl:web navigation), so the server renders the right content. Details: creator 2026-09-25: "that needs a hl:web fix the host needs to be passed on". Today gitoria works around it with a browser script (host.js); it is removed in gitoria#16.

Taken. Rule, same as session: a page or shell component that declares a member host receives the request's host (without port) on the first load and on every navigation.

Done on branch webex-host (commit dc79965f), hl:web and hl:webex alike. Declare host = null in a page or shell component; it holds the Host header without its port (alpha.example.org:8080 → alpha.example.org), null when the request sent none.
How to test:
1. In a page component write host = null and show {host} in its View (in the reference app it is #host in the shell and #post-host on the post page).
2. curl -H 'Host: alpha.test:1234' http://127.0.0.1:<port>/posts/1. The page is rendered with alpha.test. With -H 'Host: beta.test' it shows beta.test, on the same server.
3. In a browser, open http://alpha.localhost:<port>/ and http://beta.localhost:<port>/ and click to a post in each. The navigation happens over each tab's own socket and shows that tab's host. With no socket, the POST /__hl/emit fallback uses its own request's host. Gate: node projects/framework/tests/browser.mjs runs the seven host: checks. All of them fail without the change.
