 I would point out that I'm not, in general, a complete numpty.  I've
been using Pis (and other similar things) for many many years.
  So, having found out why the above simple approach doesn't work I have
tried:-
      Use rpi-imager, wasted first attempt because it wasn't obvious where
     one entered user/password.  Second attempt seemed to boot the Pi
     OK but it never appeared on my LAN so not much help there. (At
     least my first dd copied image appeared on the LAN)
      Manually editing userconf.txt with my /etc/shadow encrypted
     password from my Linux box got to a login prompt but the password
     is somehow wrong.
 

Ah. There may be gotchas in there like EOL charaters and spaces that have to be 'just right'
I generally generate the encryption using the tools suggested.
e.g. echo 'mypassword' | openssl passwd -6 -stdin
echo 'raspberry' | openssl passwd -6 -stdin

Note you never get the same string twice...
Here is a userconf.txt with user pi password raspberry...
pi:$6$c70VpvPsVNCG0YR5$l5vWWLsLko9Kj65gcQ8qvMkuOoRkEagI90qi3F/Y7rm8eNYZHW8CY6BOIKwMH7a3YYzZYL90zf304cAHLFaZE0

     Finally I managed to get a login working by creating a
     ~/.ssh/authorized keys file with the public key from my Linux
     system in it.  Phew!
 

Ultimately that is a smoother way to access the Pi anyway
