/* ============================================================
   editorial.css — primitives for /writing/ posts.
   ----------------------------------------------------------------
   A small, reusable kit. Classes only; no layout chrome. The
   surrounding article controls width and rhythm.

     .article        — outermost wrapper, sets reading width
     .byline         — author · date · reading time, single line
     .standfirst     — drop-cap'd lede with a wider column
     .pull-quote     — italic Fraunces, accent rule on the left
     .figure         — caption underneath, "Fig. N" italic prefix,
                       source line, accessible <table> mirror
     .callout        — paper-tone aside box, never coloured
     .footnote       — superscript numeral + on-hover card
     .endnotes       — full footnote text at the foot of the post
     .topic-tag      — small monospace tag, used in archives + posts

   Motion tokens (--ease-primary etc.) live in site.css and apply
   automatically.
