/* ---------- 09 query log: each question is a record, not a stacked panel ----
   A record is two tracks wide. Track one is a sequence rail that runs the
   whole height of the record, ordinal at the top, hairline down the side;
   track two carries the command line and, under it, the stdout indented
   into the same track the way a shell prints output beneath the line that
   ran it. The question is typed at a $ prompt and its state rides inline
   right after the last word, so a record reads left to right on one line
   instead of sending the eye out to a right-hand chip. The state word only
   renders when JS is there to change it. The frame sits on carbon, so
   tokens flip wholesale via data-theme="carbon". */
