/*
 * Handover - Modernist design system, direction 1b "Console".
 *
 * Ink ground with monospace evidence: the machinery on show. Non-negotiables
 * from the system guide - zero corner radius anywhere, 2px rules and never
 * hairlines, everything flush left including button labels, accent used
 * sparingly, Archivo throughout, and a themed :focus-visible ring.
 *
 * Machine-readable detail (fingerprints, connection state, protocol trace,
 * timestamps, field labels) is set in monospace. That is the one deliberate
 * deviation from Archivo-everywhere: it is what makes the cryptographic
 * evidence read as evidence.
