/* medtech-pipeline.css - page layer for the Medtech pipeline case study (HU).
   Concept: "from a scan to a pipeline". The client builds AI imaging software,
   so the hero is a scan that detects six segments; the lead-gen chapter is a
   funnel that narrows as you scroll. Motion is scroll-driven CSS behind
   @supports and prefers-reduced-motion; without either, everything is static
   and fully visible. Chapter/rail/stat/CTA blocks mirror kekvonal.css - promote
   them to main.css as one case-study block when a third page needs them. */
