/* ============================================================
   MoorAI landing-page section system, for topic pages whose head
   carries no inline copy of it (on-device-ai-dlp,
   shadow-ai-detection-for-coding-agents, owasp-llm-top-10-tooling).
   Rules match moorai.html's inline head. Linked only from those
   pages' head fragments; scripts/check-unstyled.mjs fails the build
   if a page uses these classes without loading a rule for them.
   .reveal is deliberately unstyled: these pages ship no
   IntersectionObserver, so content must stay visible.
