We use the Codex card component for displaying widgets and content sections, but every time we merge a new patch, we end up with several visual regressions (text color changes, icon color changes, etc.). See also T337384.

This is mostly due to these classes

.cdx-card__text__description, 
.cdx-card__text__supporting-text, 
.cdx-card__text__description .cdx-icon, 
.cdx-card__text__supporting-text .cdx-icon

that overwrite both local styles, and Codex styles too.

We should avoid using the Card component, and instead favor the upcoming Codex module component (see T338015), or just use local styles.
