/* ==========================================================================
   AI Hub round 2: PRODUCT PAGE TEMPLATE (agent / platform pages, L-28).
   Used first by ai-voice-agent.html.  Loads after system.css and only adds
   what the shared system does not have.  Generic class names, so any agent
   or platform page can reuse them.  Voice-only parts are in section 12.

   Anatomy:  hero -> (proof / player) -> product diagram -> buyer questions
             -> timeline -> product UI row -> capability grid -> deployment
             -> demo video -> FAQ -> closing band
