public sealed class StyleValueParserTurns a declaration's text into something that can be interpolated.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
It has to accept both of two forms of the same value, which is the consequence of ADR-009 that the spike did not reach. ExCSS normalises what it can see, and it cannot see through a var(): color: red arrives already rewritten as rgb(255, 0, 0), while color: var(--c) with --c: red arrives as red, substituted afterwards by Vixen. Both are the same colour and a parser that handled only the first would work until someone used a custom property.
Results are cached by interned value id. A stylesheet says rgb(255, 0, 0) in forty places and they all intern to one id, so the parse happens once — which matters because this runs on every declaration of every animated property.
