/* =========================================================================
   AI CONTENT CREATION AND FILMMAKING — course page
   Header/footer/hero-frame/consult are the shared components (folds.css,
   vbs.css). This course has a real thumbnail asset
   (assets/courses/ai-filmmaking.webp), so the overview uses the tilted-
   photo split. The source page has no separate numbered module list —
   only a real production pipeline ("Ideation → Script → Storyboard →
   Frames → Animation → Edit") — so curriculum here is a step-flow
   pipeline instead of the numbered dossier used on other course pages,
   scoped under its own aif- prefix.
