Note

Low Risk
Low risk visual-only updates to homepage cards and nav dropdown icons; main risk is minor layout/icon regression across breakpoints.

Overview
Updates homepage/product cards to reduce extra vertical spacing by changing card content layout from space-between to flex-start.

Extends Card lead icon support with new community and multichain icons, updates the homepage card set to use the new icons, and adds the multichain.svg asset.

Standardizes SVG icons in the products nav dropdown (replacing larger inline SVGs with smaller “thin” variants) and adds global sizing for svg.icon-thin in custom.scss to keep icon dimensions consistent.
