/* ============================================
   PROBLEM OVERVIEW REDESIGN
   ============================================
   ARCHITECTURE: Large, scannable problem cards replacing tiny tree sidebar
   WHY: Original 9-12px text too small to read; sublines cut off
   TRADEOFF: Takes more vertical space for significantly better readability

   DESIGN PHILOSOPHY:
   - "Clinical Whiteboard" aesthetic - like a nursing station board
   - Large, bold problem titles (18-20px)
   - Clear visual hierarchy for status (included/excluded/merged)
   - Key clinical context visible without hover or truncation
   - Color-coded severity bands with high contrast
