Protocol architecture, in motion.

This page mocks the surrounding article shell so the visualization can be reviewed in context — light theme, body type, real measure. The block below is the same iframe a published post would mount, talking to this host through postMessage for height.

Six scenes, one substrate.

Each tab in the embed above is a different cross-section of the same architecture. Tabs persist via localStorage; the iframe reports its rendered height up to this host after every layout change so the surrounding column reflows cleanly. No magic numbers, no scroll-inside-scroll.
