/* ════════════════════════════════════════════════════════════════════
   OUR PROCESS CAROUSEL — index.html "From Raw Earth to Reinforced
   Tomorrow" section. Isolated component (see process-carousel.js).
   Class prefix .pcc. Same coverflow/background recipe as the "Why Join
   Us" carousel on careers.html (career-benefits-carousel.css, prefix
   .cbc) so both read as one carousel system across the site — only the
   slide size/height differ to fit the existing .pillar-card visual
   (image/icon panel + badge + body), which this component wraps rather
   than replaces, per the site's illustrated-process-card language.

   Positioning model: identical to .cbc — each .pcc-slide is absolutely
   centered and moved with translate3d/scale driven by CSS custom
   properties (--tx/--sc/--op/--z) that process-carousel.js updates per
   slide based on its circular distance from the active index.
