Yes, the cursor is on the last t at the last character of the line.

No, I want to end up with the following:

example.net
different.example.com

No, the actual content includes the ""arrow and what you're calling
meta-commentary. That (and the proceeding space) are what I wanted to
remove.

Before:

"""
example.net <-- actually important
different.example.com <-- not actually important
"""

After:
"""
example.net
different.example.com
"""

Background is I was copying and pasting content from an email (including
annotations) from a friend about domains I'm configuring for him. I
wanted to get just the domain names first \W of the line and enter them
into my /etc/mail/local-host-names file.

I was editing /etc/mail/local-host-names in vim, copied and pasted the
content from email into the terminal, and wanted to remove the annotations.

This was a one-off. But I would like to learn the vim methodology to
play Vim Golf next time I need to do it.

I have frequently (monthly if not more often) needed to do a delete with
something similar to a "gE", but stop before the word.
