3D PKI Trust Tree

Where a single TLS handshake walks one linear chain, a certificate authority's real trust store is a branching tree: one root anchors many intermediate CAs, and each intermediate anchors many leaf certificates. This simulator renders that tree in 3D and animates trust propagating outward from the root through every branch simultaneously. Revoke an intermediate CA to see its entire branch — every certificate it ever issued — turn untrusted at once, the defining failure mode of PKI compromise; expire a single leaf instead to see a failure that stays perfectly local. Orbit the camera to inspect how branch width changes the blast radius of a single compromised key.
