Add box-sizing support across the rendering pipeline so that width/height can refer to either the content-box (default) or the border-box (content + padding + border). This is one of the most commonly used CSS properties and is required by virtually every modern CSS reset. The implementation adjusts width/height resolution in block, flex, grid, and table layout engines, and defaults tables to border-box in the UA stylesheet to match Chrome/Firefox/Safari behavior. Five previously-failing WPT tests now pass and are promoted in the manifest. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
