Limitation on number of custom roles?

Hello, I am wondering if there is a back-end limitation to the number of custom roles that a community can support. I have reviewed the documentation below and didn’t find a definitive mention of this.

However, I am considering a project that would involve creating quite a few custom roles and am concerned about maxing out or breaking the system (as has happened with other Gainsight features like moderator tags). Would love to know if there’s a hard limit in advance!
