 * SOVEREIGN PROTOCOL — public site.

 * Same room as the situation room (packages/viewer/style.css, docs/architecture
 * §6.1): black ground, thin vector outlines, monospace, CRT scanlines. The
 * tokens are deliberately identical so the two halves of the site read as one
 * installation — what changes here is that this side has to be *read* for
 * minutes at a time, so body copy gets a longer measure, more line-height and
 * less letter-spacing than the dense telemetry of the viewer.
