/* =================================================================
   Beveron Blog — style-v2.css
   Foundation styles aligned with /css-new/beveron-common.css.
   Tokens, typography, buttons, breadcrumb, cards, forms +
   the publication-index page module (.pub-*).
   Scope: include this file on any Blog/ page that should adopt the
   new visual language. Page content can optionally be wrapped in
   <div class="bv-page"> for stronger scoping vs. legacy Bootstrap.
