/* 管理系统 — shared styles.
 *
 * One token system, one file. Colours, spacing, radii, shadows and type sizes are
 * declared once in :root so a page never invents its own values, and every class
 * name the pages already use is preserved (the JS builds cards, chips and tables
 * from this vocabulary).
 *
 * Layout: navy sidebar + top bar on desktop; on phones the sidebar becomes a
 * drawer and every data table turns into one card per row (labels come from
 * ui.js, which copies the header text onto each cell as data-label).
