/* =====================================================================
   Product pipeline diagram (personalised-cardboard-cutouts)
   No source PNG for this one — content originated from the case study
   prose rather than transcribed from an image (both remaining case
   studies only had empty `.image-placeholder` divs). Straightforward
   linear build pipeline, no before/after moment, so no functional
   red/green accent — monochrome cream-on-black like need-to-options.
