/* ============================================================
   GoGood Groups — inline product mockups for the case study.

   Presentation tuned to match the Air Tahiti Nui & Brain Game
   case studies: Playfair Display + DM Sans, warm cream panels,
   a coral accent and a dark, glowing hero panel. Device screens
   keep their own Plus Jakarta product type. Imagery sits on the
   panels with soft shadows — no gray border boxes (CLAUDE.md).
