@@ -16,6 +16,5 @@ Do not remove or bypass these without good reason:
1. `db/index.ts` uses a `globalThis` singleton and small pool size to prevent dev hot-reload connection leaks and reduce idle RAM.
2. The NextAuth session callback caches `discordId` lookups in memory with a TTL.
3. `lib/discord.ts` caches Discord API roles/profiles in memory for 60 seconds to avoid slow repeated external calls.
4. `app/page.tsx` batches Redis unique visitor tracking and only counts when `sadd` adds a new IP.
5. Docker Compose runs a single app replica; this is intentional for low RAM usage.
6. Nginx must disable proxy buffering for the Next.js upstream so App Router streaming and Server Actions do not hang.
