/* The hidden attribute must always win over any component's own `display`

   everything here) silently ignores .hidden = true in JS — that bug bit us
   once already (the missed-panel) and was patched one-off; this single
   high-specificity rule fixes it everywhere, including every future
   show/hide toggle, instead of requiring a matching [x][hidden]{} override
   for each new component. */
