/* ==========================================================================
   Publication cards
   Boxed-card layout by default (signal / refined); the editorial theme
   overrides these into a hairline-ruled journal index. All colors, fonts
   and radii come from the theme variables defined in minimal-light.scss.

   Layout per card:
     Row 1 (.pub-meta):     [venue badge] [author status] ........ [PDF]
     Title
     Authors
     Row (.periodical):     journal, year .................. [topic tags]
