“Value not found in DB!” error for the caret-animation’s formal definition

On the caret-animation page, the missing formal definition is rendered like that:

It’s a relatively new CSS property and it seems like we could handle missing values better than this:

• Use design system colors instead of <span style="color:red;">
• Provide an actionable message that would encourage contributing the missing data

What’s interesting, caret-animation is present in the @webref/css, as well as other caret-* properties but only caret-animation is missing formal definition on MDN.

Start by reproducing the missing formal definition on the MDN caret-animation page and tracing Fred’s rendering path for values absent from @webref/css. Review how the current “Value not found in DB!” message is styled and produced; done means the missing value has an actionable contribution message and uses design system colors.
