/* =====================================================================
   LENSO ATTENDANCE — Design system
   One stylesheet, two themes:
     :root            light  → admin portal (data-heavy, long sessions)
     [data-theme=dark] dark  → kiosk (glanceable, matches the Slip Box app)

   Rules that hold everywhere:
     - status is never colour alone; every badge carries an icon + word
     - all clock values use tabular figures so columns align
     - no webfonts: a shared office phone should never wait on a font
