## Subdomain hubs render the collection's index template

When a collection set `subdomain = "x"`, its root page (`x.example.com/`) was generated with the **generic** site index template instead of the collection's own index template. For the bundled Trust Center this meant the data-driven hub (cert grid, subprocessor table, FAQ from `trust-index.html`) did **not** render on a subdomain — you got a plain listing with the bare site title.

The subdomain root now renders exactly like the collection's index page on the main domain: the same index template (e.g. `trust-index.html`, `docs-index.html`) and the same context (`collections`, `data.*`, `t.*`, `items`, `nav`), emitted to `dist-subdomains/<name>/index.html` and, per language, `dist-subdomains/<name>/<lang>/index.html`.

Main-domain behavior is unchanged, and collections that use a plain listing index keep working — each subdomain root uses whatever index template that collection would use on the main domain.
