Store the source text for unresolved CSS values instead of retaining the full parsed component value tree. Values that need the component tree now parse it on demand from the stored text. This preserves equality, tokenization, variable substitution, and Typed OM reification. Custom properties keep their original source text. Unresolved values synthesized from component values store serialized text.
