   Rounded corners on the band itself: only at its true start and end, not
   at every paragraph's edge, so consecutive .p-strong paragraphs still
   read as one continuous block rather than a stack of separate pills. A
   paragraph is "the start" when no .p-strong immediately precedes it; a
   paragraph is "the end" when no .p-strong immediately follows it. Either
