/* ============================================================
   Ambassador Group — Articles page archive (/articles)

   One efficient, beautiful page: a compact hero with the newsletter
   subscribe, a featured essay beside the start-here rail, and a dense,
   filterable, sortable library (essays + videos woven) whose controls —
   search, topic menu, format, sort — live in the archive filter bar.

   AG Design System: italic emphasis is never recolored (gold "pop"
   retired); the sort caret is a CSS-rotated border square, never a glyph;
   utility icons are inline Lucide-style SVG; Moss / Sand / Gold; self-
   hosted fonts.
