One Caddy block, both names, same root. The prerendered HTML already carries
<link rel="canonical"> and og:url pointing at the primeintellectgrowth name on
every route, so the alias does not split search ranking or leave a shared link
ambiguous about which site it belongs to. Verified byte-identical: both
hostnames return the same sha256 for /demos/wordle.
Worth recording why the alias failed before this rather than 404ing.
lumbridgecorp.com resolves on a WILDCARD, so every subdomain of it points at
cloud-2 whether or not Caddy knows the name. DNS completes, TLS opens, Caddy
finds no certificate for that SNI and aborts the handshake — the browser reports
ERR_SSL_PROTOCOL_ERROR, which reads as "the site is down" rather than "wrong
hostname". primeintellectgrowth.com has no wildcard, which is why the canonical
name needed an explicit A record.
deploy.sh now smoke-tests the alias too: if the block is ever edited to drop the
second name, the failure mode is a TLS error, and nothing else would catch it.
The live block is mirrored into deploy/Caddyfile.demo so the config is
reviewable in the repo rather than only on the host.
