/* ============================================================
   AI PILLAR PAGE — V5 FINAL SPACING REFINEMENTS
   Purpose:
   - Bring the TOC and AI Topics sections closer together.
   - Tighten selected section transitions without making the
     page feel compressed.
   - Preserve the centered card treatment introduced in V4.
   - Keep desktop/tablet/mobile side margins unchanged.
