public sealed class ComputedStyleCacheMakes equal computed styles be the same object.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
A dictionary keyed by the style itself. Interning is what turns "these two elements resolved to the same thing" from a claim into a pointer, and it is the precondition for every cheap thing downstream: reference-compared invalidation, a sharing cache that can key on a parent style, and a layout pass that can skip a subtree by comparing one word.
Nothing is ever evicted. The set of distinct computed styles in a UI is bounded by the stylesheet rather than by the element count — that is the entire premise — so growth is bounded by the thing that would have to be reloaded anyway. Clear is what a stylesheet reload calls.
