   NOTE ON LICENSED TEXT
   The Mapi licence forbids modifying the instruments, and CSS
   counts: never apply `text-transform` (or `font-variant:
   small-caps`, or `::first-letter` tricks) to .qtitle, .opt span,
   .intro or .legal. Those elements carry verbatim licensed text.
   Uppercase decoration is only allowed on labels we author
   ourselves and write in caps in the markup.
