/* ============================================
   BUG FIX: Explore page gap between filter tabs and feed
   The .main-content flex child stretches to sidebar height
   (align-items: stretch default). CSS Grid's default
   align-content: stretch then expands grid tracks,
   creating a large empty gap. Fix: pack tracks to start.
