/* Any author `display` rule outranks the UA stylesheet's [hidden]{display:none},
   so an element can carry the hidden attribute and still render. That bit the
   Walk-2-only preference question: fieldset.q sets display:flow-root (to keep
   the floated <legend> inside its box), which re-showed the block on Walk 1 as
   an empty REQUIRED question. Screens and conditional blocks are toggled via
   .hidden throughout, so this has to win globally. */
