/* Inline Footnotes — reference marker, tooltip, end-of-article list.
   Enqueued only on entries whose content carries the [nota] shortcode.

   Re-skin through the --footnote-* properties in the theme's :root; never
   re-declare these classes in a theme. Unset, each one falls back to the
   matching ali-blocks --block-* token (so a site running ali-blocks is themed
   for free), then to a neutral value:
     accent        marker ink, back link, open-marker fill
     accent-ink    marker ink while its tooltip is open
     accent-soft   marker hover fill, :target highlight in the list
     ink           strong text (back-link hover)
     muted         list text and heading
     rule          list top border
     tip-bg / tip-text / tip-link   tooltip panel
     num-bg / num-text              number badge in the tooltip
     radius, shadow, font, scroll-offset (clears a sticky header) */
