- Two new stub rows now bookend each section's rail. The top cap is a 4px-high TR whose rail TD carries border-top-left/ -right-radius so the rail's top end visually rounds off. The bottom cap is an 18px-high TR with border-bottom-left/ -right-radius so the rail's tail tapers into a rounded stop beneath the last card. - The chevron arrowhead now lives in its own TR with no rail border, sitting 14px below the rounded rail-end and another ~18px of cell height below that — visibly separated from the rail rather than sitting flush against its tip. - Chevron's horizontal offset shifted from -38 to -37 (one px right) and SVG width bumped to 26 to give the arrow a little more visual weight at its new lower position.
