   Written plainly, `ul[class], ol[class]` is (0,1,1) — an attribute selector
   plus an element — which BEATS any single-class component rule (0,1,0). Five
   rules in this theme were silently losing their padding to it, including the
   procedure carousel's 50px side padding and the footer's spacing; the symptom
   is a declaration that is present, served, last in the cascade, and still
   computes to 0.

   Inside :where() the same selector matches identically at specificity 0, so a
   component rule always wins. It still beats the browser default, because an
   author rule outranks the user-agent sheet whatever its specificity. */
