Architecture Rules

If you are changing architecture-sensitive code:

1. Read ARCHITECTURE.md.
2. Read CONVEX_RULES.md.
3. Use the nearest package or app README.md.
4. Keep surfaces thin and push durable business behavior into the owning package, server boundary, or Convex module.
5. Keep Partners-owned data out of Anan.
6. Keep Anan workspace authorization and OAuth grants inside Anan.
