     * A bare string, not `oneOf` — and this reverses finding #79 deliberately, so

     *
     * #79 was that `use()` threw on any name it did not know, and this call sits
     * in `connectedCallback`, where a custom-element reaction's exception is
     * *reported globally rather than propagated*: `<arc-icon-library
     * name="feather">` raised during element upgrade, nothing at the call site
     * could catch it, and the element's connect was abandoned partway through.
     * `oneOf(['phosphor', 'lucide'])` fixed that by normalising anything else to
     * the default before `use()` could see it.
     *
     * 4.7 removed the throw — libraries register themselves now, so `use()` takes
     * a name whether or not its pack has been imported yet, and the complaint
     * comes from `get()`, which can say what *is* registered. That also makes the
     * enum wrong rather than merely unnecessary: the set of valid names is open,
     * and `oneOf` would silently rewrite a consumer's own registered library to
     * `phosphor` — the same blank-icons-and-silence failure #79 was about, aimed
     * at the other end.
