 *
 * Exposes the exact surface `pixi-reels` uses internally (`add`, `remove`,
 * `deltaMS`) plus a manual `tick(deltaMs)` method so tests can advance time
 * deterministically without depending on requestAnimationFrame.
 *
 * ```ts
 * const ticker = new FakeTicker();
 * const reelSet = new ReelSetBuilder()
 *   .ticker(ticker as unknown as PIXI.Ticker)
 *   ...
 *   .build();
 *
 * ticker.tick(16);  // advance one frame
 * ticker.tickFor(500);  // advance 500ms in 16ms frames
 * ```
