/*
  Bold the user's input lines in UnetStack shell transcripts (```unetsh blocks)
  so they stand out from the shell's output.

  In an unetsh block, command / continuation lines are tokenised into <span>s
  (every character carries a class — keyword, string, number, operator, comment,
  the "> "/"- " prompt marker, and plain input text as class "va"), while output
  lines are emitted as bare text with no inner <span>.  Bolding the token spans
  therefore bolds whole input lines and leaves output untouched.  The line-wrapper
  spans carry an id but no class, so span[class] targets only the token spans.

/* plain input text is tagged "va" purely to give it a span to bold; it should
   keep the normal text colour rather than the theme's variable colour */
