/* The two fold-outs under a reference: peer commentary and press coverage.
   ONE rule set for both, written as grouped selectors rather than two blocks
   that happen to agree - the moment they are separate they drift, which is
   exactly how commentary ended up a size larger than the coverage under it.
   Change a number here and both blocks move together.

   Everything is in px, and repeated on the li as well as the ul: themes set
   their own base size, often on li directly, where a rule on the parent loses
   to it. The disc marker is drawn at the li's own size, so that repetition is
   what keeps the bullets small too. */
