• Since the default value for 'size' has changed from undefined to 'small', consider updating inline documentation or type comments to clearly indicate this new default behavior.

const Icon = ({ cssClass = '', name, customPath, size = 'small' }: IconProps) => {

packages/assets/src/scss/_icons.scss:17

• Icon dimensions have been significantly reduced from calculateRem(32px) to calculateRem(16px). Please verify that this change is fully aligned with the new design specifications and layout requirements.

    width: calculateRem(16px);

[GrabowskiM]

as we use TypeScript both type and size accepts only specific string values, so both these conditions always be true

true probably was ok as '' won't be visible either way, but I prefer this check, it's more clear for me

adjust to other components that doesn't allow for undefined values, "default" (without size modifier) is same as "small" in css
