/* ============================================================
   VRS – AI live demos (ai-demo.js companion)
   A: .ai-card[data-aidemo] – question types in, answer reveals,
      proposal buttons actually respond. Progressive enhancement:
      without JS the cards stay fully static.
   C: #aid-agent – proactive Agent recommendations demo (AI.html).
   Revert: remove ai-demo.css/js includes + data-aidemo attrs +
   the #agent-demo-section block; cards fall back to static.
