/* ============================================================================
   CAUSTIC INTERNATIONAL - INDUSTRIAL EDGE MINIMALISM THEME
   ============================================================================
   
   Design Philosophy:
   - Sharp geometric transitions with diagonal dividers
   - Bold typography hierarchy with Poppins and Inter fonts
   - Stark red (#EF3B36) and grey (#3A3A3A) contrast
   - Asymmetric layouts with strategic white space
   - Functional brutalism - every element serves a purpose
