   Leeloo — Articles & Insights Stylesheet
   v2.css handles: white nav/footer/body theme for all inner pages.
   This file adds the .frame container and article-specific styles.

   Visual rhythm (individual article):
     nav          → #fff (via v2.css)
     hero         → #fff full-bleed band
     article body → #fff card on #fafaf8
     prev/next    → #fafaf8 with #fff card boxes
     footer       → #fff (via v2.css)

   All classes prefixed with sia- to avoid conflicts.
