/* CASE STUDY PAGES
   The page chrome (hero, fact boxes, section headings, CTA band) uses the shared
   components in src/tailwind.css. This sheet keeps what is unique to case
   studies: the numbers, goals, status table, the interactive buy box and basket
   demos (styled to look like a real shop), the evolution figures, callouts and
   checklists. Colours come from the global tokens; stock status colours are below. */
