I manage brands for other organizations — how does that work?

If your organization manages others, each one has its own brand kit and can inherit from yours: anything it has not set falls back to your published kit, so a new organization is on-brand from day one. You can lock specific fields — a logo, a primary color, the brand name — and a locked field keeps your value no matter what the managed organization sets. And you can propagate: push your brand down to some or all of them at once, either filling in only what they have left blank (their own choices survive) or resetting their values to yours. You can include the brand voice, and choose whether the change lands as a draft they review or is published straight away.
