First note: After switching laptops, didn't notice that my commits were no longer verified. Sorry for that, is fixed now.

Second note: I have no idea why commit dbbb2a6 suddenly caused the issues with CommunityTools that it did. AFAIK no CommunityTools files were affected by that commit, yet here we are.
I did manage to solve the build issues with e269787, so there's that.

Why KeystaticFreelancer and Freelancer? Should be just one.

What is the id? Keystatic ID or Freelancer ID? Just add the id directly as variable to freelancer.

In types.ts, keep the original order.

Either use url?: string; or url: string | null not both/mixed (preference tot he 1st).

For filenames: no spaces, and lowercase.

Check if we can config/limit the branches.

By default, Keystatic creates the filename based on a single field. First and Last name are split into 2 fields, so it required some additional logic to create a filename based on 2 fields.
