Riot API routing
Region probe
Attempts all 16 configured LoL servers with your current API key. Use this to see which regions Riot has enabled on your product key versus which ones the app already exposes (10 in the player form).
Hits each LoL platform with your server-side RIOT_API_KEY: platform status, regional account lookup, and match-v5 ids. A 404 or 400 on the probe calls means the route is enabled; 403 means Riot has not granted that routing on your product key.
Enabling a newly usable region in the app still requires updating src/lib/regions.ts (available: true). This page does not change production config automatically.
