 * A `ReelSymbol` implementation that does no rendering at all.
 *
 * It creates a `Container` for its `view` (so the Reel's child-tree logic works)
 * but never paints anything. This lets tests build a real `ReelSet` without a
 * renderer, textures, or assets.
 *
 * ```ts
 * builder.symbols((r) => {
 *   for (const id of ['cherry', 'lemon', 'seven']) {
 *     r.register(id, HeadlessSymbol, {});
 *   }
 * });
 * ```
