Atmosplay Rate Limits

NO RATE LIMITS ARE PUBLISHED. Every surviving Atmosplay surface was read — the Android, iOS and Unity SDK READMEs and their English GitHub wikis, and the publisher Help Center (English guides.md and Chinese 系统使用手册.md) — and none states a request quota, a window, a burst allowance, a throttle, or any rate-limit response header. There is no 429 in the published error table; the closest published signals are SDK status codes 2005 "no ad" (no fill), 2007 "timeout error" and 2008 "server error", none of which denote throttling. The Report API, which is the one surface that would plausibly carry limits, documented only "Signature is used to verify permission" as its interface limit — and its reference lived inside the now-offline publisher dashboard, so nothing more is recoverable. Honest zero, not an unchecked field.
