/*
 * Lane 2 additions to the verified milestone-6 visual system.
 *
 * Every value here is one of milestone 6's own tokens. No new palette, no new
 * type scale, no decoration: this file only lays out the two surfaces milestone 6
 * has no component for — the lane/wallet bar under the header, and the
 * transaction rows an on-chain lane produces. Everything else in the lane 2
 * console reuses `.surface`, `.metric`, `.data-table`, `.status`, `.state-panel`,
 * `.definition-list` and `.button` exactly as milestone 6 defines them.
