/* admin.css — shared styles for the admin multi-page area (admin-*.html).
 *
 * Build-step 71 split the former single-page admin.html (JS tab switching) into
 * one standalone HTML page per area. This file holds the styling every one of
 * those pages shares (extracted verbatim from admin.html's old inline <style>),
 * so the look stays identical across pages without duplicating ~630 lines of CSS
 * ten times. The grouped sidebar's item styling (.sidebar-nav-*) lives in
 * shared.css and is shared with the in-app help page; only the .admin-nav-sidebar
 * positioning/collapse below is admin-specific.
 *
 * All colours come from the shared theme variables in shared.css, so light and
 * dark both work. Loaded after shared.css on every admin page.
