/* Numbered citations + Sources panel in blog and tradeshow bodies
   (App\Services\CitationMarkup). Loaded by blog_detail and tradeshow_detail only.

   Colours come from the body tables (navy header #2d557a, row tint #e6edf3), so
   citations read as reference marks, not as content links. Contrast (WCAG AA):
   #2d557a on #e6edf3 6.6:1 · white on #2d557a 7.6:1 · chip in a table header:
   inherits the header's text colour on a 16% tint of it (white on navy ≥ 5:1). */
