The "team badge" explanation for consumer groups is the clearest I've
seen this concept explained. And using a separate group for the
dashboard bridge vs the alerter is a great real-world example of why
that distinction matters, reusing one would've silently split the data
between them.
The ADVERTISED_LISTENERS gotcha (connects fine, then fails on the
second hop) is also worth calling out, that's a very specific failure
mode most tutorials skip.
