/* ========================================
   RELATED POSTS — LAYOUT FIX 2026-05-01 (v2)
   Validiert nach 3-Agent-Review.
   1) theme.json core/group leak: AUSSEN UND INNEN auf 0 zuruecksetzen
      (innere wp-block-group erbt sonst auch 64px → Phantom-Whitespace).
   2) Kategorie-Tag horizontal mittig + display:inline-block am <a>
      sicherstellen (Defensive gegen kuenftige Block-Style-Drift).
   3) Inhaltsbereich Bottom-Padding reduzieren, da Datum entfernt.
   4) Title flex-grow:0 mit !important — die existierende Regel
      .related-posts .wp-block-post-title (Zeile 525, Specificity 0,2,0)
      wuerde sonst per cascade-tie mit unserem 0,2,0-Override gewinnen
      sobald jemand eine Regel zwischen einbaut. !important macht's robust.
   5) Multi-Kategorie-Defensive: ab dem 2. Badge ausblenden + Separator weg.
   6) Grid-Fallback wenn weniger als 3 Cards vorhanden.
   7) Print: Related-Posts ausblenden.
