        /* Viewer toolbar prev/next-episode buttons (.paginate.v2 around #N).
           Same class family as the bottom-of-list pager but rendered at
           toolbar scale. Three things needed:
           1. Size the buttons explicitly (the disabled .pg_next.dim is a
              <span>, not <a>, so it picks up no pill rule from the generic
              .paginate a rule — zero dimensions, chevron invisible).
           2. Match parent line-height to button height so the text "#N"
              and the buttons share the same line metrics — without this,
              vertical-align:middle still leaves the buttons below text.
           3. Replace the thin ‹ › guillemets the generic .paginate rule
              injects with the heavy chevron ornaments ❮ ❯ (same as the
              snb scroll arrows), and absolutely-position the pseudo
              inside the button — centering becomes bulletproof regardless
              of font metrics. Specificity beats the generic rule. */
