/* XCET shared UI, v1.0.0
   The components every XCET tool shares: page shell, header, side menu, tabs, cards, buttons, fields, tables, badges,
   banners, dialogs, toasts, action bar. Built on xcet-tokens.css (load that first). Copy unchanged into each repo; put
   anything tool-specific in the tool's own stylesheet, loaded after this one. Distilled from the Bulk Asset Record Tool
   (app-shell, components, buttons and ui-shared CSS) with the accessibility fixes in the guidelines applied.

   Contents: 1 Base · 2 Shell and header · 3 Side menu · 4 Tabs · 5 Cards · 6 Buttons · 7 Fields · 8 Messages and badges
             9 Stat tiles and chips · 10 Tables · 11 Empty, progress · 12 Dialogs · 13 Toasts and action bar */
