Gives users a low-friction way to tell us they're using coder_eval, and
records logo/trademark permission explicitly so an adopter list can be
published without guessing at consent.

+        Thanks for using coder_eval! Adopter entries help other teams see the project is
+        real and in production, and they tell us which use cases to keep supporting.

+        Everything below is optional except the organization and how you use it. We only
