Chrome --headless can dump the dom to the command line. Set a virtual time budget in vms [?] for the js to settle down and then do stuff.

Html() {
  chromium \
    --headless \
    --incognito \
    --dump-dom \
    --virtual-time-budget=999999 \
    "$1"
}

HtmlToText() {
  lynx -stdin -dump -nolist
}

This has “peculiar” uses. Fun fact: invoking the name of chromium around normal people confers alien–like status.
