/* 
 * Z-INDEX STACKING SOLUTION (Clean Approach)
 * 
 * This solution uses proper CSS specificity and stacking contexts instead of !important:
 * 
 * 1. Created new stacking context with `isolation: isolate` on .development-process
 * 2. Used higher specificity selectors (.development-process .process-step .step-number)
 * 3. Set timeline elements to z-index: -1 (behind everything in stacking context)
 * 4. Set step numbers to z-index: 100 (foreground)
 * 5. Set step content to z-index: 50 (middle layer)
 * 
 * This ensures timeline lines stay behind step numbers across all responsive breakpoints
 * without using !important declarations, following CSS best practices.
