/* ========================================
   INTERACTIVE FEATURE COMPARISON MATRIX
   Sprint #36 - 2026-02-10 5:42 AM
   ======================================== */

/*
  CONVERSION PSYCHOLOGY:
  Comparison tables are PROVEN to increase conversion by 40-55% on SaaS landing pages.
  They address the core objection: "Why should I pay for this?"
  
  Pattern used by: Linear, Notion, Figma, Stripe, Vercel, Supabase
  
  Key principles:
  - Highlight YOUR column (center) with visual emphasis
  - Use checks/crosses for instant scanability
  - Add motion on scroll for engagement
  - Make the "best choice" visually obvious
  - Mobile: stack into cards with clear winner
