/* =====================================================
   ARTICLE COMPONENTS
   =====================================================
   Every selector here is scoped under .article-body, and
   every class is prefixed art-.

   WHY BOTH:
   The old article vocabulary reused names the rest of the
   site already owns — .eyebrow, .tag, .badge, .dot, .col,
   .snippet, .table-scroll. An imported article using any of
   them picked up header and card styling and looked broken.
   That is the "CSS overlaps with website style" problem.

   A prefixed, scoped name cannot collide with anything, now
   or when the site design changes later.

   The old class names still work — they are styled in
   style.css under .prose and are untouched, so every
   already-published article renders exactly as before.
   Use art- names for everything new.
