Module rate_limit 

Tiered rate limiting middleware.

Classifies request paths into three tiers (auth, standard, public) and applies per-tier rate limits. Supports in-memory and Redis backends.

OPTIONS requests bypass rate limiting entirely to avoid breaking CORS preflights (browsers treat 429 on preflight as a network error regardless of CORS headers).
