   Full-Page Sections
   
   Usage Guidelines:
   - Use section-callout for major results, top performers, key findings
   - Use section-wide for tables and data that need more horizontal space
   - Major result showcases should use gradient backgrounds
   - Regular content stays in standard article sections
   
   Full-Width Technique:
   - width: 100vw makes the section viewport width
   - margin-left: calc(-50vw + 50%) breaks out of parent containers
   - This works by shifting the element left by half the viewport width,
     then shifting it back by half the parent's width
   - position: relative and left: 0 ensure proper alignment
   - Parent containers must have overflow-x: visible for this to work
   - To prevent horizontal scrollbars, we use a specific technique below
