ForgeMark Marking Demonstrator

Set a marking policy on the left and watch the classification banner, portion tags, and derivative-authority block render on the sample frame. The publish preflight at the top updates live: break a rule and watch the gate that catches it flip to blocked.

This mirrors ForgeMark's shipped marking logic and color tokens. The real system runs inside the private CourseForge editor and publisher. Read the ForgeMark whitepaper.
