/* =============================================
   MD Hair Preview AI — Frontend Styles (v2.1)
   "Smart unified" — defends against theme/Elementor overrides.
   =============================================

   Strategy:
   • Every rule is scoped under #mdhair-app for natural isolation.
   • Layout-critical rules on the comparison cards use higher specificity
     (#mdhair-app .mdhair-comparison-card.mdhair-comparison-card) and
     !important on the few rules that themes commonly fight us on
     (object-fit, object-position, width, height).
   • Modern browsers: aspect-ratio for guaranteed 1:1 cards.
   • Older browsers: padding-bottom fallback.
   • Soft brand-aligned card background so any rare gap looks intentional.
