/* =========================================================================
   Flip Pricing Cards - Contact Form Integration
   ========================================================================= */

/*
  COMPONENT STRUCTURE:
  - .pricing-cards-container: Grid wrapper
  - .pricing-flip-card: Individual card wrapper (overflow: visible for badges)
  - .pricing-flip-card-inner: Animation container
  - .pricing-flip-front: Front face (visible by default)
  - .pricing-flip-back: Back face (hidden, contains form)
  
  Z-INDEX USAGE:
  - .pricing-flip-front: z-index: 2 (default visible)
  - .pricing-flip-back: z-index: 1 (hidden behind)
  - .plan-badge: z-index: 10 (floats above card)
  - When flipped: front becomes z-index: 1, back becomes z-index: 2
  
  ANIMATION:
  - Fade + slide transition (not 3D flip)
  - Click-only (no hover trigger)
  - Controlled via .flipped class on .pricing-flip-card-inner
