		 * Localize the prelude name of `@keyframes` / `@counter-style` / `@container`: `options.string` takes the first string, `options.identifier` the first ident (a `RegExp` skips matching keywords), `:local()`/`:global()` count as found; top-level `var()`/`style()` dashed idents are always ICSS-processed.
