Query.publicResolvedThemePreview
Public: same shape as publicResolvedTheme but selects the theme the preview token grants access to instead of the store's live theme. Returns null on missing/expired/revoked token. Single round-trip: token validation + bundle fetch are atomic so the storefront can't race a token expiry. NO AUTH — the token IS the credential.
