The apex `A` records are still needed even though `www` is canonical — they are
what lets GitHub answer on the apex in order to redirect it.

`docs.lynkrobotics.org` is unrelated and should be left alone.

**Still worth doing:** the apex has no `AAAA` records, so IPv6-only visitors
cannot reach it. Not urgent — every other visitor is fine, and `www` already
has IPv6 — but add them when convenient.
Both record types are needed on the apex. The `A` and `AAAA` records let GitHub
answer there over IPv4 and IPv6 respectively, purely so it can issue the
redirect to `www`.
