/* venode console chrome v1.
 *
 * Operations-style site shell shared by every public page. Borrows
 * directly from the references that informed the Plenum mock-up:
 * PyroSim, ParaView, Smokeview, VS Code, AutoCAD.
 *
 * Three fixed strips wrap the page:
 *   1. Top toolbar (vn-topbar)      — file/breadcrumb meta strip.
 *   2. Left activity rail (vn-activity) — workspace navigation, VS Code style.
 *   3. Bottom status bar (vn-statusbar) — section, view, units, AS check.
 *
 * A coordinate triad floats over the lower-right corner. The page content
 * sits in the middle of these strips and keeps the existing typography.
