-## Two hostnames, one root
-
-Both names serve the same build. The prerendered HTML carries
-`<link rel="canonical">` and `og:url` pointing at the **primeintellectgrowth**
-name on every route, so the alias does not split search ranking or make a shared
-link ambiguous about which site it belongs to.
-
-⚠️ **`lumbridgecorp.com` resolves on a wildcard.** Every subdomain of it points
-at cloud-2 whether or not Caddy has a block for it — so an unconfigured or
-mistyped name completes DNS, opens TLS, finds no certificate for that SNI, and
-fails the handshake with `ERR_SSL_PROTOCOL_ERROR`. That reads as "the site is
-broken" when it means "that is not a site". `primeintellectgrowth.com` has no
-wildcard, which is why the canonical name needed an explicit A record.
-
-`deploy.sh` smoke-tests the alias for exactly this reason: if the block is ever
-edited to drop the second name, the failure is a TLS error rather than a 404,
-and nothing else would notice.
