   MK Universal Catalog Pro V1
   Theme: 02 - Luxury Fashion
   File: themes/theme02/assets/css/style.css
   Purpose: Complete design system for this theme. Uses the same class
            structure as every other theme (shared template scaffolding)
            but a completely distinct visual identity: serif editorial
            headlines, a black/gold/cream palette, and wide magazine-style
            spacing in place of Theme 01's minimal rounded-corner look.
