/* ========================================
   MUKI SOLUTION - PAPER KIT THEME
   Colors, type and component accents tuned to match Paper Kit 2's design
   language (loaded via wwwroot/lib/paper-kit). Most components (.card,
   .btn-primary, .btn-outline-primary, .title, .page-header, ...) now come
   straight from paper-kit.min.css / bootstrap.min.css (BS4) - this file only
   supplies the brand palette, the page furniture Paper Kit doesn't ship
   (navbar gradient, hero, footer, chat widget, stat counters, timeline) and
   a couple of small Bootstrap 5 utility-class shims still present in markup.
