/* =====================================================================
   PREMIUM ENHANCEMENT LAYER  —  KIETO PORTFOLIO
   Loaded AFTER style.min.css + custom.css so it can refine without
   breaking the base template. All accent usage flows through the
   existing --kieto-accent token system so the style-switcher stays
   the single source of truth for colour.
   ---------------------------------------------------------------------
   Sections:
     0  Foundations (tokens, fonts, reduced-motion guards)
     1  Typography upgrade (display font + scale + rhythm)
     2  Card depth system (layered, tinted shadows)
     3  Hero refinement (texture, layout, CTA, image)
     5  Magnetic + micro-interactions
     6  Section header polish
     7  Portfolio + skill + service polish
