Character codes in typed text; the site and relay at app.kokkoja.com

With the Text tool, Klammertext's codes give letters a keyboard lacks:
^o" is ö, ^s^ ß, ^a1 ā, ^130ED^ a code point of 4 to 6 digits,
^9053 53EF^ a sequence, ^^ a caret, replaced as each code is completed.
The public site and relay moved to app.kokkoja.com; the old name
redirects.  The Markdown documentation is withdrawn from the release
while it is converted to Klammertext; the README's links to it are
stale until then.
