Reviewer's Guide

Adjusts the NGINX Lua valkey handler used for proxying Blizzard API requests so that Swagger and Redoc documentation continue to render correctly even when upstream responses are rate-limited.

File-Level Changes

Change	Details	Files
Update the Lua valkey handler logic so that documentation UIs (Swagger/Redoc) are not broken when Blizzard returns rate limit responses.	Modify response handling to distinguish between API calls used by Swagger/Redoc and general API traffic when upstream responds with rate limiting status codes Adjust forwarding or transformation of rate-limited responses so that Swagger/Redoc assets and JSON specs still load successfully Possibly refine error/status mapping or headers to avoid breaking the documentation frontend when rate limiting occurs	build/nginx/valkey_handler.lua.template
