Catalog SEO assigns (canonical / hreflang / og) for the public shop LiveViews, multi-domain aware.

The canonical host per language comes from the workspace-wide config :phoenix_kit, :canonical_host_resolver, {mod, fun} MFA (nil or absent ⇒ the site-wide PhoenixKit.Utils.Routes.url/1 base, today's behavior). On a language's home host its own locale prefix is stripped — the language is that domain's default.

hreflang inclusion for slug-translated pages is decided on the RAW slug map (Map.has_key?(entity.slug, lang)) — SlugResolver silently falls back to the default-language slug, which must never produce an hreflang entry mislabelling the fallback URL as a translation.
