* feat(dom-css): compile component variants into state styles
Code export needs a component's variants as one markup tree whose look follows the control's state. stateStyles keeps the rest variant as the base and turns each other variant into only what it changes, under the data-state, data-disabled and interaction conditions Reka and Radix set, or a data attribute for other variant properties. Layers only some variants draw stay hidden where absent. stateStylesToCSS writes a stylesheet with readable classes and stateStylesToTailwind writes utilities behind state variants.
* refactor(dom-css): build state stylesheets with the CSS object model
The stylesheet was assembled from strings with JSON-quoted attribute values. It is now built with @acemir/cssom, which rejects an invalid selector and prints the declarations, and attribute values are escaped as CSS strings by cssesc. The object model loads lazily, as for font-face rules, so stateStylesToCSS is async.
* refactor(dom-css): split state styles by step and require a rest variant
model.ts mixed reading conditions, projecting and merging variants, and comparing styles. They now live in conditions.ts, layers.ts, and model.ts, with the types in types.ts. A layer only some variants draw keeps the style of the variant that adds it, so no separate first-style pass is needed. A set with no rest variant now has no state styles, instead of using a checked or hovered variant as its rest look.
