/* Ambrose UI system (2026-11-04)
 *
 * One home for the layout and components that the redesigned pages were each carrying inline copies of: warm paper,
 * white cards, ink + signal orange. Everything is namespaced `ui-` so it can sit next to a page's legacy CSS without
 * either side changing the other. Tokens come from shell.css; nothing here defines a colour of its own except the
 * status tints (which shell.css has no token for).
 *
 * Usage:  <link rel="stylesheet" href="/os/ui-system.css"> + <script src="/os/ui-system.js"></script>, then call UI.lock()
 * to turn on the desktop page-lock (the page never scrolls; the rail and the panel do).
 *
 * Anatomy of a page:
 *   .ui-app            grid: .ui-rail | .ui-main            (.ui-app.no-rail = a single column)
 *     .ui-rail           full-height left panel (.ui-rail-head, .ui-rail-scroll, .ui-item rows)
 *     .ui-main           flex column: .ui-hero? .ui-tabs? .ui-toolbar .ui-stats  .ui-scroll  .ui-pager
